Women in NANBIOSIS part 4: María Sancho’s journey from nanomaterials to cancer therapy

Our expert in nanocarriers talks about her journey from biotechnology to cancer therapy, an example of passion and perseverance in science.

February 2024, I3A/CIBER-BBN, Zaragoza (Spain)

The silence of the meeting room is only broken by the constant purring of the heating system. A large square table made of dark wood fills the entire room almost completely. Its dimensions are too extensive for anyone to reach its center. One may wonder, how many passionate conversations about the next step to take in countless research projects have been witnessed by these four walls?

The door swings open briskly, and a familiar face crosses the threshold with a smile. We have shared lab bench in the past, and María, with her memory honed by years of dedication to her craft, remembers that brief period of our lives surprisingly well. We greet each other warmly. She radiates energy and passion for what she does.

The interview begins.

Hello María, tell us a little about yourself.

“My name is María Sancho, I studied a Bachelor’s Degree in Biotechnology at the University of Zaragoza, just the second generation after its implementation. I did my bachelor’s thesis at the Institute of Nanoscience and Materials of Aragon (INMA), and this contact with nanotechnology made me decide to continue expanding my training in this field and try to dedicate myself to science and research. Then I did the Master’s in Nanomaterials, the ‘NanoMat’, at INMA, as it complemented my biochemistry-oriented training very well with the materials aspect of the Master’s.

After I finished both my bachelor’s and master’s thesis at INMA, I had the opportunity to apply for (and obtain) a prestigious State doctoral scholarship with Jesús Santamaría as Principal Investigator. This allowed me to do my thesis here in Zaragoza, which I defended in December 2020. For the past three years, I have been in Milan, at the Mario Negri Institute of Pharmacological Research, with Luisa De Cola. Her outstanding work focuses mainly on nanomaterials, different from those I worked on during my thesis, allowing me to train in a highly complementary area.”

So, you’re currently doing your postdoc in… Italy?

“No, no. I just returned last October, once again, to Jesús Santamaría’s group, with the goal of establishing here in Zaragoza as a researcher… if possible (laughs).”

“I am fortunate to be able to devote myself to something I am passionate about. Research is something I enjoy every day.”

—Dr. María Sancho, Researcher at Unit 9.

What motivated you to choose a career as a researcher?

“Ever since I was very young, I’ve been an inquisitive, curious, and creative person. I got into research spontaneously, although it’s true that in my family we always talked about scientific research, my father was a teacher and a geologist himself. Over time I’ve realized that science has a vocational component, it requires a lot of dedication, but it excites me. During my high school studies, I was clear about choosing the scientific path. After finishing high school, I pursued a degree in Biotechnology, which had been implemented in Zaragoza just a year before. During my studies, I witnessed the significant advances of the great nanotechnological revolution of recent years. My interest grew only stronger and I decided to do my doctoral studies.

In 2016, I obtained a prestigious and competitive contract for the so-called University Professor Training State program ‘FPU’ from the Ministry of Education. This allowed me to carry out my doctoral thesis at the University of Zaragoza, in a leading and excellent research institute like INMA. So, I could say that I didn’t hesitate to start my career as a scientist. During this period, I was fortunate to have thesis supervisors who transmitted their passion and enthusiasm for research to me. This undoubtedly encouraged me to continue developing my scientific career. Today, I can say that I am fortunate to be able to devote myself to something I am passionate about. Research is something I enjoy every day.

Could you share with us a bit about your area of research and the projects you are currently working on?

“In general terms, my research focuses on developing small containers, which we call nanoparticles, with nanometric dimensions. This means that they are much smaller than human cells. Specifically, my project is based on developing nano-containers capable of directing and transporting drugs and anti-tumor molecules in the body. This way, we load these nanoparticles, which have therapeutic properties, inside vesicles produced by our own body, so that they can kill and act against tumor cells. We hope that these nano-containers with therapeutic properties, once injected into the bloodstream, can reach their target cell and then release the drugs loaded inside them. When we take a painkiller for example, only a small part of the drug acts to relieve that headache. In this project, what we aim for is the possibility of using less therapy and directing it selectively to the tumor. In this way, the maximum possible amount of the supplied active compound reaches the cancer cells. Furthermore, by being encapsulated in these nano-containers and selectively reaching tumor cells, it would ensure avoiding side effects and not affecting other organs.”

What have been the greatest challenges you have faced as a woman in your research field?

“From my experience, to this day, I have not faced challenges attributed to gender. I believe the greatest challenges I have encountered have been common to those of my male colleagues, and are linked to being ‘young researchers’. I associate these challenges with the fact that research is not only an occupation of nearly irrelevant importance in Spain, but also one of great uncertainty, and it is not sufficiently recognized. It requires great dedication, many hours of work, sometimes yielding good results, and other times not. Furthermore, there are few and highly competitive State grants in Spain that allow you to dedicate oneself to research continuously and steadily. As you progress in your research career, you spend more time on bureaucracy, seeking funding and more projects. And the truth is that in the vast majority of cases you won’t get them. This derives in less hours in the lab doing the experiments. I believe there are not enough resources available today.”

Have you ever experienced any type of gender bias or added difficulty in your scientific career? How have you addressed this situation?

“From my experience, up to this day, I have not encountered any additional difficulties compared to men. Nor have I experienced any situations of inequality. However, I do believe that all young researchers, in general, both women and men, face significant challenges in advancing and developing their professional careers. In fact, many of the colleagues I encountered while doing my doctoral thesis have been forced to abandon their scientific careers.”

Could you tell us more about your challenges as a young researcher?

“One of the biggest challenges has been having to go abroad to continue my scientific career. This requires great effort and dedication. Already during my doctoral thesis, I undertook two stays abroad. One of them was for three months at ETH Zurich. The other one lasted for two months at Politecnico di Milano. After completing my doctoral thesis in 2020, I followed the advice of my supervisor to go abroad for at least two more years to continue my postdoctoral career. It was not an easy decision, as I embarked on my journey amid the COVID pandemic, but I had the opportunity to get a job interview with Luisa De Cola, the leader of a globally renowned group.

Although it has been a path full of changes and uncertainty, I don’t feel like I have had to give up anything I wanted in order to pursue my work. However, it’s true that research has taken my time away from other activities. I have probably missed out on doing some things. I have spent two and a half years away from my family and friends in order to continue my education. All this with the goal of returning to Spain as a researcher, which wasn’t even guaranteed. In my case, a few months ago, I managed to secure a postdoctoral grant to develop a research project for four years in Zaragoza, so it has been worth it. Specifically, I have returned to INMA to join the group led by Jesús Santamaría (who was also my thesis supervisor), one of the top scientists in Aragon. He has been involved and supported me throughout my journey as a researcher, even while I was abroad, and he advocated for my return to INMA.”

What advice would you give to young women who are considering pursuing a career in science?

“Firstly, if you’re considering it, I believe that research, like other professions or activities, often reveals its fascination only once you experience it from within. Additionally, it’s a profession that greatly nurtures the mind, fills you with stimuli… and it’s very enriching to formulate a hypothesis and be able to test it in the laboratory. I think it’s something rewarding not only professionally but also personally. In addition, it is a profession that allows you to travel to other countries, get to know other cultures, people who started as colleagues and then became friends. On the other hand, all the teamwork it requires is very satisfying. The individual work you do in the laboratory is later contrasted with others. And yes, it is true that there are bad days when things don’t go your way, but when something works out, it more than makes up for it.”

This is great timing for my next question. Have you had any ‘Eureka’ moments? What do you consider your greatest achievement, or something you feel particularly proud of?

“In 2019, there was a moment when there was a cocktail of people who were working exceptionally well and enthusiastically, of the results we were obtaining, and of the project… All of this allowed us to publish my first paper in Nature, which was highly cited afterwards. This was a really cool moment for me.”

Your very own first-author scientific publication… in Nature. And you were still doing your thesis!

“Yes, I was still working on my thesis. But of course, this achievement is not mine alone. It’s very much intertwined with all the teamwork behind it. It’s a publication that goes hand in hand with projects that Jesús Santamaría had at that time, which allowed us to test all the ideas we had. And of course, thanks to the work of many people, like Santamaría himself, Víctor Sebastián, Pilar Martín, and international collaborators we had in Edinburgh… In short, it was a cocktail that allowed us to do something that didn’t exist in the field. No one had tried vesicles with this type of nanoparticles to make catalysts before! It was a group effort, and very satisfying for all of us.”

If someone in your family, who is not a researcher, asked you about your publication in Nature, how would you explain it to them?

“Well, from a scientific point of view, we managed, for the first time, to encapsulate palladium nanosheets in lung cancer exosomes. These nanosheets are harmless to our body, but they can catalyze a reaction that halts the growth of cancer cells.”

And, as you well said, it was a group effort. What was your contribution to that publication?

“What I did was isolate the vesicles and develop a system to produce the nanosheets inside the vesicles without altering their properties. The thing is, up until that point, when attempts were made to attach these nanosheets to the vesicles, the vesicles ceased to be selective to the cancer they were targeted to. This was because the methods used were too aggressive, causing significant damage to the vesicles. What we did was to develop a very gentle method to achieve high encapsulation efficiency and maintain their ability to selectively reach the tumor. On the other hand, our collaborators in Edinburgh studied all the catalysis and reaction dynamics. So, when we administer a systemic prodrug, it’s harmless throughout the body. But as soon as it reaches the tissue where the cancer is located, this prodrug is catalyzed by the nanosheets into its toxic derivative, acting only on the tumor cells.”

That’s brilliant. Plus, you won’t have the biocompatibility issues seen in other drugs.

“Exactly, because the exosomes you use are naturally produced by the cells themselves. That’s the difference compared to other forms of encapsulation. We only tested it at the in vitro level with cells. But imagine being able to use the patient’s own exosomes to encapsulate the nanosheets. This is a starting point to explore this novel therapy further.”

And indeed, it ended up being published in Nature.

(laughs) “Yes, when such a crazy and bold idea gives you such a good result, it kind of gives you the motivation you need to keep going. And that curiosity we were talking about earlier, which I believe every scientist has, produces a very satisfying and inspiring feeling.”

What changes would you like to see in the scientific world to promote gender equality?

“I believe that calls and projects are being adapted more and more to consider maternity leave periods, etc. This allows individuals of all genders to compete on equal terms. However, it’s true that in higher-level positions, certain roles are still more commonly occupied by men. Although, it’s also true that there are more and more female principal investigators (PIs) leading research groups. I think in the future, we’ll see more and more women leading research groups as PIs.”

How do you think we can encourage more women and girls to participate in science?

“There are many science outreach activities highlighting the role of women in science or showcasing prominent female scientists. Activities like this one, promoted by CIBER-BBN, or by other institutions, are important. In my own Institute (INMA), numerous such activities are conducted, which are part of the objectives included in its Strategic Plan. From the scientific community, we are very interested in promoting interest in science, communicating the importance of scientific advances in different research areas, and conveying the daily work carried out at a prestigious research center. At my institute, we strive to make women and girls visible, inspire them, and promote their participation in science. This includes talks, exhibitions, roundtable discussions, competitions, scavenger hunts, activities in pubs, and a series of scientific talks aimed at schools, as well as in-person workshops.

I don’t think we’re doing it wrong. What is more, I think since COVID people have become more aware of the importance of scientific development. A few years ago, few people knew what a PCR was or the effort behind vaccine development. I believe it is important that society as a whole understands what these careers entail.”

That’s all. Thank you very much, María. It’s been very interesting.

“I’m glad!” (laughs)

Women in NANBIOSIS part 3: Professor Fany Peña, her insights in research, parenthood, and persistence

Prof. Peña gives us her insightful point of view in overcoming challenges, embracing passion, and cultivating collaborative success towards career estabilization.

February 2024, Unizar/CIBER-BBN, Zaragoza (Spain)

The echo of our footsteps returns from the high ceilings filled with electrical conduits and gas pipes. An alarm sounds in the distance, while the warmth of the Zen Garden located in the center of the R&D Building reminds us once again that peace and progress will never be at odds.

We continue forward across the maroon floor, towards one of the access gates that separate each wing of the building. After crossing it, and almost without warning, the echo disappears with the slam of the heavy security door behind us. Now, the noise of the machines muffles our voices and footsteps as we walk through one of the many laboratories of the building. The numerous panels and posters, along with the bustling activity, make it clear that this is a place where science is the undisputed protagonist.

With a strangely welcoming feeling, we enter the spacious laboratory of Professor Estefanía Peña. The light in the room is bright, neutral, and aseptic like the complex machines that adorn it. High-precision devices, some venerable with a history of witnessing scientific breakthroughs, and others, the product of cutting-edge engineering, now contributing to new frontiers.

Two people await us in the room: a young technician, quiet and discreet, and his boss, a woman who, despite, or perhaps as a consequence of her undeniably established scientific career, radiates youthfulness, energy, and determination. Both kindly welcome us to their realm, where they rule over the complex machines. The woman quickly grabs the reins of the conversation, filling the room with her overwhelming, yet approachable personality.

Prof. Peña introduces herself: “Fany, just Fany is fine. That’s how everyone calls me.”

The interview begins.

Alright, Fany, tell us a little about yourself and your research group.

“My group focuses on computational modeling of the human body and pathologies. We also design implants and devices to correct pathologies. We work on real-time simulation and Artificial Intelligence.”

What motivated you to choose a career in research?

“Since I was very young, I’ve loved mathematics, physics, experimenting, asking questions like ‘why does the apple fall?’, and also because of the influence of my family.”

Could you share with us a bit about your research area and the projects you’re currently working on?

“My group is quite large and has three main lines of research: artificial intelligence applied to biological engineering, prosthetic design, lenses, muscle fatigue, and, in the case of those closest to me and Dr. Martínez Barca, the mathematical study of cardiovascular pathologies: myocardial infarction, how these lesions affect the heart, atheroma plaque, and devices to try to correct vessel obstruction. Recently, we’ve been working on modeling aneurysms in collaboration with groups from Val d’Hebron Hospital.”

Have you had any Eureka moments in your career? What do you consider to be your greatest achievement or contribution in your field at a professional or personal level?

“Probably my first doctoral thesis. Feeling capable of teaching and mentoring someone was a significant milestone for me. The topic was about carotid stents.”

What have been the biggest challenges you’ve faced as a woman in your research field?

“The biggest challenge has been balancing personal life, especially family life, with work. Especially when you’re young. I’m someone who, when I dedicate time to something, I dedicate it in full. Moreover, the moment when you have to dedicate much more time to a research career starts right after you finish your doctoral thesis until you reach professional stabilization. And that’s usually the period when you start a family. That’s a key moment and the greatest difficulty that, I believe, 99.9% of female researchers face.”

How do you think these barriers can be overcome?

“To be honest, I acknowledge that the role of a mother is almost irreplaceable. However, I believe that society is still not prepared to understand that women, besides being mothers, also want to do other things. It’s not just a problem of task distribution; I think nowadays roles in motherhood and fatherhood are quite shared, especially among young people. I believe it’s more of a social issue, meaning that even in terms of state aid aimed at encouraging motherhood, it’s scarce. Imagine, in other countries it’s inconceivable not to have a daycare or a similar service at the workplace. I think the role of a mother is very important, but…”

…having a daycare at work helps, right?

“It helps quite a bit, yes.”

“The most important thing in your professional career is to dedicate yourself to something you love (…) that’s incredibly important from a professional point of view.”

—Prof. Estefanía Peña, Scientific Coordinator of Unit 13.

What advice would you give to young women considering pursuing a career in science?

“Go for it! The most important thing in your professional career is to dedicate yourself to something you love. I mean, family and your personal life bring the greatest happiness, yes, but I know many people who work in something they don’t like, either because they haven’t found work anywhere else or because they opted to study something easy back then, even if they didn’t like it that much… I believe that working in something you love allows you to do things much better, and that’s incredibly important from a professional point of view. Study and do what you love, and if you love science… go for it!”

And what about all those girls who doubt?

“Yes… the truth is, from the talks I’ve given at schools, the response from girls often is ‘Phew!’ And usually, the female ratios, in my case as an engineering professor, are very, very low. But success rates, the highest grades… there’s no distinction there. It’s a 50/50. That means there’s no added difficulty, beyond the intrinsic difficulty of a science career, which both men and women will feel equally. Probably women will have more advantage since, for whatever reason, we tend to be able to focus more and be, as we use to say in Aragon, ‘more stubborn’. It doesn’t really matter much if subjects are more difficult because when you really like what you do, you don’t mind dedicating more time to it.”

What support have you received throughout your career that has been particularly useful?

“My colleagues, without a doubt. I’ve had people I’ve worked with and continue to work with since I started my thesis. There are people I’m still working with whom I started working with 25 years ago. And I have the utmost confidence that if I’m on maternity leave, nothing will go wrong. Or that if one of my colleagues fails, the rest of us will always be there. That’s extremely important. I don’t think it’s necessary to mention specific names. Science is very collaborative, whether from a teaching or research perspective. I always say ‘tanto monta, monta tanto’.” [Interviewer’s Note: a historical idiomatic expression when both king and queen held equal authority and power in the newly unified kingdom of Aragón].

Very Aragonese phares as well.

“Yes, very Aragonese.”

Thank you very much for your time, Fany.

“Thank you very much, Gabriel.”

Women in NANBIOSIS part 2: Ana Martín, and her Multi-degree Journey

We ask Dr. Martín about her innovations in cancer treatment with nanoparticles, in the context of her collaborations with NANBIOSIS.

This is part of a series of interviews to several female researchers within the context of International Day of Women and Girls in Science 2024 and Woman’s Day 2024. For more interviews, visit our news section here.

February 2024, INMA-CSIC/CIBER-BBN, Zaragoza (Spain)

We are walking through the tall corridors that connect the numerous blocks of the large R&D Building, located near the Río Ebro Campus of Unizar. This building is a conglomerate of institutes, laboratories, and research groups. In its dead center, open to the outdoors, a Zen Garden welcomes us, like an oasis of peace in the midst of this whirlwind of information, advancements, and scientific progress.

We enter the meeting room. The lights are flooding a large dark table surrounded by chairs. After a few minutes, Ana arrives. We greet each other warmly. It has been a long time since we last saw each other, perhaps since college? With a nervous laugh, she confesses, “Having a microphone in front of you is quite intimidating…”. She laughs again.

I consider making a joke right after the first question, in an attempt to reassure her. But I quickly change my mind as soon as she starts talking. Her nerves have completely dissipated, and her words, once shaky, now fill the recording with a confidence I didn’t expect. The confidence of someone who carries behind them a career as varied as it is fascinating.

The interview begins.

Well, Ana, tell us a little about yourself.

“My name is Ana. I have a degree in Veterinary Medicine, a degree in Biochemistry, and a Ph.D. from the University of Zaragoza. Currently, I work in the NFP group. My chemist colleagues synthesize nanoparticles, and I use them for anti-cancer treatments.”

What motivated you to choose a career in science?

“Since I was little, I’ve always been very interested in natural sciences. I’ve always been intrigued by how biological systems work, and over time, I became interested in pathology, the cause of diseases, and their treatment. That’s why when I had to choose a career, I chose Veterinary Medicine and, later, Biochemistry.”

Could you share with us a bit about your research area and the projects you are currently working on?

“Since I started working in research, I have been involved in the field of biomedicine, but the areas have been progressively changing. My career began in the field of aging and vascular diseases. Later on, I applied this knowledge to cancer research, which is the field I am currently working in, using nanoparticles as an anti-tumor treatment.”

What nanoparticles do you use?

“We use nanoparticles that, through catalysis, consume glucose and produce toxic species, inducing cell death specifically in tumor cells. We have many types of nanoparticles, especially by combining different types of metals. We introduce them into extracellular vesicles, which have tropism towards tumors, significantly improving the treatment compared to free nanoparticles.”

And what types of cancer do you treat?

“We use different cell lines from lung cancer, colon cancer, cervical cancer, brain cancer… We aim to create a treatment that is not specific to one type of cancer but can be applicable to many types of tumors. And high glucose consumption is something that tumors have in common.”

What have been the greatest challenges you have faced as a woman in the field of research?

“I believe the most difficult challenge has been balancing a scientific career with personal life, specifically with motherhood. When you work as a scientific researcher, there is never a perfect time to have children. You know that your career will be put on hold for a while, and research never stops, so there is a constant fear of falling behind. But as a scientist and a mother, I think one should never give up on motherhood because of it. In the end, everything is achievable, and personal life should never be sacrificed for professional life.”

Have you experienced any gender bias or added difficulty in your scientific career? How have you addressed this situation?

“In my case, I have been fortunate and I don’t believe I have experienced any gender bias. However, I do know of cases involving female colleagues who have encountered it.”

“There are challenging moments during a scientific career (…), but in the end, persistence pays off.“

—Dr. Ana Martín, collaborator scientist in Unit 9.

What advice would you give to young women considering pursuing a career in science?

“My advice would be to enjoy the work in research. We have to remember that it is one of the best jobs out there; we are doing something for society, to improve it, whether working in biomedicine or other areas like technology. There are challenging moments during a scientific career, times when it’s difficult (due to lack of funding, opportunities, etc.), but in the end, persistence pays off. And if for some reason it doesn’t work out, all the knowledge gained will still be very useful in other areas.”

And what advice would you give to those who are unsure?

“Well, if they’re not sure… before diving into a doctoral thesis, they should visit laboratories, see how things work here, and choose something they enjoy. Because you’re going to spend a lot of time working on it, and the environment you’re in is very important.”

How do you think gender stereotypes can be overcome in your research field?

“I don’t believe there are gender stereotypes. However, it is true that currently, positions of greater responsibility are often held by men. In my opinion, equal opportunities should be given to men and women, and the time taken by women for their careers due to motherhood should not be penalized. This way, we can finally break the ‘glass ceiling’, and young people can also have female role models.”

And what about being a mother?

“In other countries, I’ve seen people having children during their doctoral thesis, and that’s unthinkable here. I believe the measures taken so far are just a patch and don’t fully compensate.”

What do you consider your greatest achievement or contribution in your field of study?

“Personally, my greatest achievement was obtaining a project on breast cancer in which I was Principal Investigator. As for my greatest contribution, I couldn’t say for sure. I believe everything I have done has contributed a little bit to research on vascular calcification, aging, and cancer. Perhaps it may seem somewhat insignificant, but it could be very important in aiding future research.”

What support have you received throughout your career that has been particularly helpful?

“The support of my family and my partner has been indispensable throughout my career. I also appreciate the support of the Government of Aragon and the European Union for the funding I received during my predoctoral and postdoctoral stages.”

What changes would you like to see in the scientific world to promote gender equality?

“I would like to see women not have to postpone or give up their personal lives for their work. I believe that, with the support of institutions, anything is achievable, as is the case in other European countries.”

How do you think we can encourage more women and girls to participate in science?

“I truly believe that there are more women in science than men. The problem is that leadership positions are almost never held by women, perhaps because many women end up sacrificing their careers for their personal lives, and that shouldn’t happen. We should break the glass ceiling and allow women to access leadership positions so that girls have examples of female scientists to follow and don’t think that science is only for men.”

It’s been a pleasure to see you again and chat with you, Ana. And thank you for your time.

“Thanks to you too.”

Women in NANBIOSIS part 1: Anna Aviñó, from Curiosity to Innovation

Anna Aviñó speaks about her journey as a researcher and her captivating oligonucleotides.

This is part of a series of interviews to several female researchers within the context of International Day of Women and Girls in Science 2024 and Woman’s Day 2024. For more interviews, visit our news section here.

February 2024, IQAC-CSIC/CIBER-BBN, Barcelona (Spain)

Could you share with us a bit about your research area and the projects you are currently working on?

I am a chemist specializing in nucleic acid chemistry. These compounds are wonderful, I would say unique; not only do they contain genetic information, but they are also involved in countless biological processes. My focus lies in synthetic and structural studies of small nucleic acids, known as oligonucleotides.

And these compounds, what are they used for?

Oligonucleotides can adopt different structures, including canonical duplexes as well as other secondary structures like quadruplexes and triplexes, the latter being particularly important in many diseases. I apply my chemical knowledge to generate and evaluate therapeutic oligonucleotides (such as antisense, siRNA, aptamers). Furthermore, oligonucleotides are so versatile that I also use them as recognition elements in various biosensors to detect pathogens, disease-related genes, etc.

“Oligonucleotides (…) are recently being approved as new advanced gene therapies for many diseases, including rare and cardiovascular diseases.“

—Dr. Anna Aviñó, scientific coordinator of Unit 29.

What motivated you to choose a career as a researcher? What have been the biggest challenges you have faced as a woman scientist?

I wanted to understand what things are made of, how medicines are made… I am currently 55 years old with a long scientific career, but it has never been easy to balance top-level research with family life. I have to thank CIBER as it’s the longest contract I’ve had, but I also have to say that I haven’t had opportunities for career advancement within it.

Have you experienced any kind of gender bias or added difficulty in your scientific career? How have you addressed this situation?

I haven’t faced any added difficulty per se, but the reality is that in my research center, the principal investigators are predominantly women with few family responsibilities.

How do you think gender stereotypes in the scientific field can be overcome? And what advice would you give to young women considering a career in science?

I think that stereotypes can be overcome by promoting unbiased education in schools regardless of the field of study. I would definitely encourage young women and advise them not to be afraid to pursue positions of responsibility.

What do you consider to be your greatest achievement or contribution in your field?

The oligonucleotides, which are my area of study as I mentioned, are recently being approved as new advanced gene therapies for many diseases, including rare and cardiovascular diseases. I can say that I can synthesize drugs in my laboratory, and furthermore, I believe I am the person who has conducted the most synthesis of these products in Spain!

What support have you received throughout your career that has been particularly helpful?

As I mentioned, thanks to CIBER, I continue to be a researcher. However, I am currently in a delicate situation because my principal investigator is retiring, and I don’t know how my scientific career will continue.

What changes would you like to see in the scientific world to promote gender equality? How do you think we can encourage more women and girls to participate in science?

The scientific world is not particularly biased in terms of gender equality. However, leadership positions tend to be held by men, even though more women are starting careers in research. Regarding encouraging more women, as I mentioned, education. Education is the key.
