I am an Assistant Professor in the Network Science Institute at Northeastern University--with appointments in Marine & Environmental Sciences, Physics, and Health Sciences--and am also the Chief Data Scientist at Dharma Platform. My research spans a broad range of topics in complex systems and network science, including: infectious disease dynamics, forecasting and predictive modeling, complex network analysis, disease genomics and transcriptomics, outbreak surveillance, social networks, gene network evolution, and decision making under uncertainty. Our group, the Emergent Epidemics Lab, approaches these topics by investigating questions using mathematical and computational methods from biology, statistics, physics, applied mathematics, and computer science.
Through collaboration with laboratory, field, and public health researchers, the mathematical and computational models we develop are interrogated with novel experiments, evaluated on new data sources, and applied to public health and clincal problems. Our surveillance research, for example, is done in close association with state, national, and international public health agencies and has led to substantive changes in surveillance practices. I believe this type of collaboration between scientists and public health decision makers is critical for efficient, effective outbreak preparedness and response.
Beyond disease, the group's research has focused on a variety of topics, including animal movement and group dynamics; traffic routing; the effects of environmental toxins on behavior and neural biology; and models of spatiotemporal variation in tree density and fruiting phenology. If you’re interested in working with us, please contact me via email. For more detailed information, please see full-text versions of our articles and my current curriculum vitae.
