RESEARCH INTERESTS

My research interests are focused on the interaction between animal populations and aquatic environments. Specifically, I enjoy researching the influence that anthropogenic factors have on movement patterns and population dynamics for species of interest. It is my hope that determining the influence of anthropogenic factors, as they relate to interaction between animals and their habitat, we will be better prepared to conserve and rehabilitate the aquatic environments studied.
