Some of my projects in the field of Epidemiology:

A Sequential Combinatorial Decomposition of Disease Incidence Curves

We developed a new, sequential, combinatorial decomposition technique for understanding how infectious disease spreads among different subpopulations and across communities or ecosystems over time. (PDF of the paper published in Mathematical Biosciences)

This is in collaboration with Elena Naumova at Tufts University School of Medicine.

Apparent Seasonality in Infectious Disease Incidence

We are investigating the influence of social interaction among etiologically distinct subgroups on disease incidence rates, examining whether or not we can predict observed seasonal trends in infectious disease as emergent properties of the system.

This is in collaboration with Elena Naumova at Tufts University School of Medicine.

The Influence of Social Behavior on the Magnitude of Infectious Disease Outbreaks

We are developing a dynamic network-based model to study the impact of shifting social affiliations within groups on the spread of disease.

This is in collaboration with Kah Loon Ng at National University of Singapore and DIMACS.

Social Immunity and Colony Immunocompetence in Termites

We developed a series of agent-based cellular-automata models to investigate the relative efficacy of a variety of societal structures and individual behaviors in aiding population survival under disease threat from a fungal pathogen in colonies of damp wood termites.

This is in collaboration with James Traniello and Daniel Calleri at Boston University, and with Rebecca Rosengaus at Northeastern University.

Environmental Epidemiology: A Two-Stage Wavelet Analysis

We developed a two-stage wavelet decomposition method to analyze the impact of local temperature and precipitation on incidence of waterborne disease in human populations on a variety of temporal scales.

This is in collaboration with Elena Naumova and Jyotsna Jagai at Tufts University School of Medicine.
