What is your role at your work?

As an early-career investigator in health metrics, I lead research on the burden of non-communicable diseases and cardiometabolic risks in Latin America. I coordinate country-specific teams to disseminate findings from the Global Burden of Disease Study (GBD) and inform health policy and regional priorities.

How did you get interested in your career path?

While studying human nutrition, I developed an interest in the determinants of metabolic and cardiovascular health and the interplay of risk factors and health systems. I was inspired by the academic and research environment in the Endocrinology and Metabolism Department at the National Institute of Medical Sciences and Nutrition in Mexico. My undergraduate thesis explored the relationship between diet and reactive hypoglycaemia (DOI: 10.24875/GMM.M17000007), which led me to pursue a master’s and PhD in nutrition.

What are you most proud of in your career or otherwise?

I’m proud to advance research on global health priorities and disparities at the Institute for Health Metrics and Evaluation. Collaborating with international researchers and policymakers to address local health challenges, such as hypertension and other non-communicable diseases, has been a key highlight of my career.

What important career challenges have you faced and how did you overcome them?

Balancing professional growth, personal life, navigating immigration processes, and overcoming impostor syndrome has been incredibly challenging. I leaned on resilience, supportive mentorship and meaningful personal relationships to persevere and grow.

What advice would you give your younger self?

Trust the process, embrace uncertainty, and don’t hesitate to seek help, mentorship, and collaboration. Communicate early and often—research is a team effort, not a solo endeavor.

Key contributions include studies on the burden of disease and a meta-analysis on the effect of systolic blood pressure on ischemic heart disease.

Have you had any significant career mentors? If yes, please provide further details.

Yes, mentors have guided my initiation and growth as a researcher. Barbara Vizmanos, my master’s thesis director at the University of Guadalajara in Mexico, believed in me and my capabilities, supporting my research career from the start. Rafael Lozano, Professor Emeritus at the University of Washington and my PhD advisor, has motivated me by offering valuable insights into fostering leadership and collaboration opportunities in global health. Emmanuela Gakidou, Professor at the Institute for Health Metrics and Evaluation (IHME), has also been incredibly supportive throughout my journey, particularly in my first year as an Acting Assistant Professor.

How can we support the next generation of women scientists?

To support the next generation of women scientists, I think it is essential to lead by example with a commitment to equity, ensure fair representation, and appropriately recognize contributions. I advocate for closing the gender pay and maternity gaps, fostering safe and inclusive environments where women can thrive both professionally and personally, acknowledging the full spectrum of women’s work, and providing mentorship that extends beyond scientific expertise to include skills in finance, leadership and communication.
