Principal Investigator

Yvonne (Bonnie) Maldonado, MD

Senior Associate Dean, Faculty Development and Diversity, Professor of Pediatrics (Infectious Diseases) and of Health Research and Policy

Yvonne (Bonnie) Maldonado is Professor and Chief of the Division of Infectious Diseases, Department of Pediatrics at Stanford Medicine. She also directs Stanford's Global Child Health Program and serves as the Medical Director of Infection Prevention and Control at Lucile Packard Children's Hospital at Stanford. The research Dr. Maldonado has conducted has been focused on epidemiologic aspects of viral vaccine development and prevention of perinatal HIV transmission. A major project has been to identify the molecular epidemiology of factors affecting the immunogenicity of oral polio vaccine (OPV) among children living in developing areas of the world, where OPV immunogenicity is poor. Dr. Maldonando's group has identified several factors which affect the poor immunogenicity of OPV and will conduct clinical studies to attempt to improve immunogenicity. The group works on improving understanding of the transmission and circulation of polio vaccine-derived viruses, which may cause polio, and how to use this information in global eradication of polio. Her lab is also leading efforts to improve diagnostics and understanding of SARS-COV2 transmission.

Clea Sarnquist, DrPH, MPH

Clinical Associate Professor, Pediatrics- Infectious Diseases

Dr. Sarnquist focuses on applied teaching and research on the development, implementation and evaluation of interventions to decrease gender-based violence and prevent HIV infection, especially among adolescents and children. She is particularly interested in rights-based approaches that tackle the comlex interplay of factors that lead to poor health for many children and families. All of her work is applied, with direct links to health practice and policy, and usually performed in conjunction with non-governmental organization and government partners. She works both globally and in the U.S., with a focus on sub-Saharan Africa. Read More.

Jonathan Altamirano, MS

Senior Research Data Analyst, Pediatrics- Infectious Diseases

Jonathan received his B.A. in Human Biology and M.S. in Biology from Stanford University. He is originally from Houston, TX and is a native Spanish speaker.  His interest in medicine, public health, and global child health comes from living in Nicaragua as a child and both seeing and experiencing the effects of tropical vector-borne diseases. He supports and manages research projects in both the Global Child Health program, as well as the Stanford Medicine Office of Faculty Development and Diversity. He hopes to go to medical school, and continue to work in global child health as an MD. He is the recipient of the 2017 Stanford Pediatrics Rising Star Award. Read more about Jonathan in this 2018 profile on the Scope Blog.

Sean Leary

Life Sciences Research Professional, Pediatrics- Infectious Diseases

Sean is Dr. Maldonado’s laboratory manager and a researcher in her lab group.  The lab has been working toward the goals of polio eradication and better understanding the current COVID-19 pandemic worldwide by looking at the transmission and genomics of the viruses. He is interested in solving global health issues to improve people’s lives.
