Mark Henderson, Ph.D.

My current research focuses on the interactions between Pacific salmon and the environment. My approach is to use data collected in the field to develop and inform ecological models. Modeling techniques I have used include statistical analyses, mark-recapture, growth models, bioenergetics, and individual-based models. These models can then be used to study how environmental changes affect fish behavior and population dynamics.
