I serve as the Associate Director of Science for IVAC (International Vaccine Access Center). I am an epidemiologist with a focus in the technical analytical challenges of policy-driven research pertaining to the design, conduct and analysis of epidemiological studies and clinical trials that evaluate vaccines and vaccine-preventable diseases. I direct the analysis of a 7-country pneumonia case-control study (PERCH) to determine the causes of pneumonia in developing country settings to guide the development of new pneumonia vaccines and treatment algorithms. Other primary data collection projects include: assessing the impact of pneumococcal conjugate vaccine introduction into national immunization programs in Kenya, The Gambia and India on pneumococcal disease; evaluating the value of new diagnostic tools such as antigen-based blood tests and pneumococcal serotype-specific urine antigen tests to improve sensitivity and specificity of pneumococcal disease detection in pneumonia patients, and digital auscultation to determine pneumonia etiology. I also work on collaborative efforts with other Departments and Institutions to develop new diagnostic and analytical tools, such as an analytical method for estimating pneumonia etiology and computer-automated and standardized interpretation of chest x-rays. Secondary data analysis projects include global meta-analytical projects to estimate disease burden and vaccine impact, such as estimating the burden and serotype distribution of pneumococcal, Hib and meningococcal disease among children and adults, and evaluation of pneumococcal conjugate vaccine schedules and products to inform country decision-making regarding these programmatic choices.
