The Interactive Effects of Invertebrate Trait Variation and Environmental Characteristics: Implications for Food Webs

Research: My research focuses on how environmental characteristics like food and habitat availability in streams affect macroinvertebrate traits at the species and community level. I am also examining the effects of this trait variation on macroinvertebrate food web structure and dynamics.

Effects of riparian disturbance on reciprocal aquatic-terrestrial energy flows

Research:  My research focuses on understanding how riparian disturbances associated with invasive plant (Amur Honeysuckle) and insect (Hemlock Woolly Adelgid) species affect reciprocal aquatic-terrestrial energy fluxes and food web structure in stream-riparian ecosystems.

How does artificial light at night alter fish vision?

Research: Artificial light at night (ALAN) has become one of the most pervasive sources of pollution worldwide. A growing body of research indicates that ALAN poses a significant threat to global biodiversity, but research on the consequences of ALAN for aquatic ecosystems remains limited. My masters research investigates impacts of long-term exposure to ALAN on the visual performance of Bluegill (Lepomis macrochirus), a common sunfish in freshwater systems of eastern North America and a visual predator.  My findings will help target lighting thresholds necessary to minimize disturbance to aquatic ecosystems and contribute to informing roadway-lighting management schemes.
