PhD, Johns Hopkins University, 2000


My research interests include the epidemiology of vaccine-preventable infectious diseases and the methodologic issues pertaining to the design, conduct and analysis of epidemiologic studies and clinical trials. Currently I serve as the Associate Director of Science for IVAC (International Vaccine Access Center). Current projects include the PERCH Study to determine the causes of pneumonia in settings representative of developing countries to guide the development of new pneumonia vaccines and treatment algorithms for 2015 onwards, estimating the burden and serotype distribution of pneumococcal and meningococcal disease among children and adults, measuring the impact on disease burden of pneumococcal conjugate vaccine use in Kenya and The Gambia, and evaluating the value of antigen-based diagnostic tests in blood to improve sensitivity of pneumococcal detection in pneumonia patients.
