With this interview we want to know the vision of a woman who is at the epicenter of scientific activity:
The pandemic has been an abrupt turning point for humanity. Where have you seen the best reactions?
There are many people dedicated to the cause, but as far as my environment is concerned, the researchers, in general, have had an attitude of maximum dedication to the work, which has resulted in a very high level of creativity and performance. Researchers are experiencing the problem very intensely, getting involved not only with our minds but also with our hearts.
What things have positively surprised you?
I am positively surprised by the transparency of the pharmaceutical industry and also by the advantage that being in the European Union has offered us to access vaccines. At the country level, although I have always trusted in the good work of the Spanish Agency for Medicines and Health Products (AEMPS), I have been very pleased to see its good coordination with the Carlos III Health Institute and with other departments of the ministries of health and research. Finally, on a scientific level, I am very pleasantly surprised that vaccine coverage is proving to be so high.
How has your way of seeing the world changed?
This stage has made me think more about the globality of the world and the need to address this globality in a comprehensive way. The solution to problems cannot be local or partial, it must have a global approach. More than ever, we must feel like citizens of the world, with the responsibility that this entails. Also individually, I have been more aware of the vulnerability of the human being.
What innovations would you highlight in your sector or field of work?
Although we were not prepared for a pandemic in terms of the structure and logistics of the health system, we were prepared from the perspective of scientific and technological development and innovation, worldwide. Advances in the last half century in areas such as biotechnology, omics sciences and technologies, artificial intelligence and nanotechnology have paved the way for researchers involved in developing new treatments and vaccines.
2021 is being a year full of uncertainties and also hopes: Why do you think we will move forward?
We will move forward thanks to science, the kindness of many people and the love that unites us to human beings. These three engines will help us overcome the malignancy of the virus and the selfish and irresponsible attitudes of some people.
When do you trust that the great uncertainties (health, social, economic) will be cleared?
With the vaccination of a significant percentage of human beings, we will relax, we will interact more socially, and this will have a positive impact on health and the economy. However, I hope that the level of alert in relation to future medical challenges, which will undoubtedly come, will remain at a certain level in terms of support for research and for our health system. The future of the economy lies in research and the promotion of talent and the future of our health as well.
Responding to the unbeliever: What are your great motivators/goals to continue at the foot of the cannon?
The research collective is more at the foot of the cannon than ever in the time frame that I have had to live. The incentive is clear: to help our society; In my case, in the field of science and education, can there be a better incentive? I believe that there is no doubt that the essential pillars of any society are health and education. I feel privileged to have this opportunity.
In what field do you think the most important innovations will arrive, or should a bet be made in the coming years?
I would like to see the innovations of the coming years have an impact on the world in a global way because, in the end, we all share a planet that we have to take care of from the perspective of prevention and also treatment. I hope that there will be important innovations in the field of education, extracting the best of new technologies, in the field of health of people (biotechnology, nanotechnology, artificial intelligence, genomics) and in the field of the health of the planet (green energy, the fight against microplastics, the reduction of wild consumerism… etc).
