I currently lead clinical research in East and Southern Africa that is focused on improving prevention and care of infectious diseases in pregnancy.  I serve as a member of the Research Governance Committee at LSHTM and an Academic Editor for PLOS ONE.  Before moving to the UK, I was the Health Advisor for USAID in Rwanda where I led operational planning for the President's Malaria Initiative.  Prior to this, I was the Director of the Americas Region at International Services of the American Red Cross where I spearheaded partnerships with the Pan American Health Organization / World Health Organization, the UN Foundation, and US Centers for Disease Control and Prevention, to scale up the community component of the Integrated Management of Childhood Illness. Before this, I worked in the United States Senate as a staff member, overseeing legislative affairs related to health service delivery in rural areas.  I was a Peace Corps volunteer, as well, serving in the Republic of Kiribati, Central Pacific.

I earned my PhD in clinical epidemiology from the London School of Hygiene & Tropical Medicine and the University of London, UK, and my MPH from The George Washington University in Washington, DC, USA, in International Health Policy and Programming.  I was also a Visiting Fellow in the Department of Health Policy and Management at the Harvard T.H. Chan School of Public Health in Boston, MA, USA.
