Dr. Powell's research focuses on mathematical biology at organismal scales and above, including: developing tools in applied mathematical, nonlinear evolution PDE, asymptotic analysis and homogenization, dynamical systems, nonlinear parameter estimation and uncertainty quantification. Mathematical Ecology: dispersal and demographics of organisms, spatial spread of populations, movement ecology and habitat usage. Mathematical Entomology: predictive phenology, thermal control of life cycle timing and dynamic aspects of adaptations to the environment, outbreak and spread of mountain pine beetles (Dendroctonus ponderosae). Mathematical Modeling: population dynamics, animal movement in complex landscapes, energetics of organisms, bird flight, industrial chemical reactions, market pricing of derivatives, and evolution of quantitative traits.
