Dr. Bellan teaches a variety of quantitative approaches in infectious disease epidemiology with a focus on data-driven mechanistic modeling. HIs teaching approach emphasizes intuitive understanding of statistical and dynamical modeling using interactive lectures, computer labs/tutorials, and realistic examples of data analysis. Dr. Bellan is particularly interested in training researchers to use simulation modeling to plan and interpret empirical studies. He is also the Program Director of the International Clinics on Infectious Disease Dynamics and Data (ici3d.org), which organizes two annual training workshops in Florida and Cape Town.
Dr. Bellan’s lab takes a broad quantitative perspective to address applied questions in infectious disease epidemiology. His research spans multiple pathogen systems (HIV, Ebola, anthrax, rabies) but is united by an overarching theme: the integration of mathematical and statistical models with empirical data to understand infectious disease processes and how to control them. By building simulation models of how diseases spread at the population level, he helps to interpret available data and to plan rigorous empirical studies. Dr. Bellan’s research particularly focuses on this intersection between epidemiological study design and transmission dynamicsâ€“that is, he aims to improve study design and interpretation by understanding the dynamical transmission processes underlying an epidemic and how they might bias studies.
