My research group is focused on developing new tools to better measure malaria transmission and determine how some people are able to be infected with malaria parasites without becoming sick. We do this by studying malaria in its natural environment, applying novel laboratory and analytical methods to high quality field studies. Most of our work is based on data and samples collected from field surveillance or clinical trials performed in malaria endemic areas, primarily sub-Saharan Africa. My current projects focus on understanding the development of naturally acquired immunity, creating novel antibody-based tools to measure malaria exposure and immunologic protection, working on improved diagnostics, and using parasite population genetics and spatial data to understand parasite transmission and evolution. My lab is based at Zuckerberg San Francisco General Hospital and Chan Zuckerberg Biohub, where I am an investigator.
