Sen Pei is an Assistant Professor in the Department of Environmental Health Sciences at Mailman School of Public Health, Columbia University. With a background in applied mathematics, network science, and complex systems, he studies the effects of environmental, social, and ecological conditions on infectious diseases using a variety of data sources, including surveillance data, human mobility, climate data, and electronic health records. He develops mathematical models and computational tools to advance surveillance, forecasting, and control of both seasonal and emerging infectious agents. His recent studies focus on respiratory viruses such as influenza and COVID-19 and antimicrobial-resistant pathogens in healthcare systems.
