Description of Research Expertise

I study the eco-epidemiology of tropical diseases. My current research uses canine rabies as a model system to understand how the social and spatial features of urban areas influence the emergence and persistence of infectious diseases.

My most recent line of research focuses on urban canine rabies. I conduct community-based surveys paired with GPS tracking of free-roaming dogs to understand the drivers of canine rabies outbreaks. My methodological interests include spatial analysis, optimization of interventions to control infectious disease, and design of community-based studies.

I am a scholar of infectious disease epidemiology with a strong background in quantitative methods, zoonotic disease ecology, and the study of complex systems. I am committed to teaching and research in public health, infectious disease, and epidemiological methods. I am well versed in designing and conducting observational and experimental community-based studies, as well as laboratory-based research. I have strong data management and analysis skills; experience with a variety of data sources.
