Experiences & Accomplishments
I am an infectious disease epidemiologist with an interest in the changing epidemiology of vaccine-preventable respiratory diseases in children. I lead field studies and employ mathematical modelling to address questions related to vaccine program performance, optimization, and equity. I have also led several public health training and capacity development efforts with several partner organizations. I have been based in South Asia for more than a decade where I collaborate with researchers from leading institutions in the region.
