My primary area of research is statistical ecology. My PhD involved developing a continuous-time (CT) framework for spatial capture-recapture (SCR) models. The CT SCR framework treats detections as a temporal Poisson process and uses an encounter rate function to model the actual times of capture. Using a CT framework avoids having to impose an artificial construct on the data for analytical convenience, allows one to learn about animal behavior, facilitates a parsimonious and flexible way to model heterogeneity in detection, and leads to a likelihood for single-catch traps.
I also work with non-spatial capture-recapture models and occupancy models, and am a core member of the Statistics in Ecology, Environment and Conservation (SEEC) research group.
