About James A. Powell

Modeling ecological phenomena, particularly those in which dispersal is crucially involved, is what gets me excited on the boundary between biology and applied mathematics. I am a 1990 PhD graduate of the Interdisciplinary Applied Math Program at the University of Arizona, where I worked on envelope equation models and transition dynamics for fluid and laser system with wave instabilities. I also honed my interest in working as a full partner with scientists and engineers using artisanal applied mathematics. When I came to USU I was introduced to the spectrum of possible ways to answer new and fundamental ecological questions using hand-built mathematical models. My background in nonlinear dynamics, asymptotic methods, and applied PDE was perfect for working on problems having to do with dispersal and pattern formation in ecological systems. My group works on a diverse array of problems, including invasion dynamics, dispersal in heterogenous environments, outbreaks of disease and pests, phenology and timing of life history. We are distinguished by interacting with disciplinary practitioners, involvement with data collection, and modeling in a data-driven setting.
