Research Interests

I am a quantitative ecologist interested in disease dynamics, community and population ecology, and species conservation.

To mimic natural hierarchical systems, I develop hierarchical Bayesian models, and I exploit data collected over space and time to separate ecological and observational processes to answer ecological questions.

My research program focuses on unifying ecological and evolutionary theory to address fundamental questions in disease ecology using field, experimental, and quantitative approaches.
