How do habitat changes affect fish populations?

Associate Professor, Fisheries and Wildlife

My research interests focus on how anthropogenic disturbances affect aquatic habitat conditions, and how this impacts fish populations. I have worked in marine, lake and stream ecosystems, and hope to continue to work in a variety of aquatic environments. My favored approach to science is to do large-scale manipulative experiments coupled with quantitative observations and analyses of population and community-level data.
