Gabe Barrile

I am an applied quantitative ecologist. I work at the intersection of disease ecology, population demography, and animal behavior, often employing data science techniques to provide evidence-based solutions to conservation challenges. I also study disturbance ecology, particularly how natural and anthropogenic disturbances influence host-pathogen dynamics. My research incorporates many taxonomic groups, from fish to frogs to finches to furry critters. Ultimately, my research aims to directly inform species conservation and management.

Population Modeling in Ecology

Developed a 3-credit graduate course on statistical modeling in population ecology. The course introduces key software packages and fundamental models used in fish and wildlife population analysis. Course content includes estimating ecological state variables (occupancy, abundance) and population vital rates (survival, recruitment, dispersal) of both marked and unmarked populations, accounting for imperfect detection.
