Research Overview

My research focuses on aquatic systems and trophic linkages that shape food web form and function in the Beaufort Lagoon Ecosystems. I am interested in determining what energy sources (e.g., terrestrial, bacterial, phytoplanktonic) fuel food webs and how these sources change through time and space. I use biomarkers (e.g., stable isotopes, fatty acids) as tools to better understand trophic connectedness and resilience of food webs.
