My research addresses the ecology and conservation of aquatic and riparian ecosystems. I employ a highly interdisciplinary approach, drawing from stream and wetland ecology, fluvial geomorphology, trophic ecology, and landscape ecology to holistically address basic ecological questions as well as applications to conservation and management. Unified by the themes of ecosystem-scale dynamics and connectivity, my principal research activities focus on ecological and biogeochemical connections between aquatic and terrestrial ecosystems, linkages between stream geomorphology and ecology, and biogeography. The following are current projects in the Stream and River Ecology (STRIVE) Lab:
Associations between fluvial geomorphology, stream equilibrium, and stream-riparian food webs in urban streams (Columbus, OH)
The role of wildfire in shaping structure and function of stream ecosystems (Yosemite National Park, CA)
River-riparian food webs, energy fluxes, and aquatic-to-terrestrial contaminant transport (Scioto River basin, OH)
Rare fish conservation in multistressor landscapes (including propagation and reintroduction; Scioto River basin, OH)
Influences of artificial night lighting (i.e., ecological light pollution) on stream-riparian biodiversity and food webs (Columbus, OH)
Impacts of hemlock woolly adelgid to coupled dynamics across riparian and stream ecosystems (OH, WV, VA)
Consequences of dam removal as a disturbance in river ecosystems (Olentangy and Scioto Rivers, OH)
Coastal-estuarine food webs across natural and artificial gradients of the Florida Gulf Coast (FL)
Phosphorus and nitrogen dynamics in non-agricultural watersheds of the Ohio River basin (OH)
Conservation of riparian aerial insectivorous birds (OH)
Collaborative, interdisciplinary efforts define the nature of my work. A project linking urban development, environmental alteration, and language change in Lithuania is an example. In addition to research, my lab group is actively involved in multiple outreach activities in and around the Columbus area.
I also serve as the Director of the Wilma H. Shiermeier Olentangy River Wetland Research Park (swamp.osu.edu). Through December 2015, I am based out of the National University of Colombia, Bogotá as a Fulbright Distinguished Chair of Biodiversity and Sustainable Development.
For prospective graduate students: I am always on the lookout for talented, motivated, and passionate graduate students. If you are interested in my lab, please send me a short description of your interests and career goals, a CV/resume, your GPA (undergraduate and graduate, if applicable), and your GRE scores and percentiles.
