People in the Pace Lab


David Seekell, Ph.D. Student

David joined the lab after completing his undergraduate work at the University of Vermont. He applies a variety of statistical approaches to the study of ecological problems. His dissertation research is focused on using statistical indicators largely developed in economics to discern early warning indicators of regime shifts. He also studies questions related to lake-size abundance distributions, virtual water, aquatic food web interactions, and the centrality of “luck” in determining fishing success.

Kyle Emery, M.S. Student

Kyle completed his undergraduate degree at the University of Virginia. He is interested in coastal marine ecosystems and is pursuing research at the Virginia Coastal Researve LTER. His work focuses on the ecology of bivalves in Virginia coastal lagoons. He is exploring the utility of the stable isotopes of carbon, nitrogen, and hydrogen for distinguishing the ecological capabilities of hard clams, oysters, and scallops. He is also assessing approaches to measuring the areal coverage of clam aquaculture production and the possible significance of carbon storage by these organisms.

Grace Wilkinson, Ph.D. Student

Grace came to Virginia after graduating from St. Olaf College. She is studying the importance of terrestrial organic matter to freshwater aquatic consumers. She is using natural abundances of stable isotopes of carbon, nitrogen, and hydrogen to test hypotheses about the variation in terrestrial subsidies of aquatic consumers among lakes.

Jessica Gephart, Ph.D. Student

Jessica graduated from Miami University in 2011, where she studied Zoology and Environmental Science, and conducted research in science education, green advertising, and carbon storage in lakes. Jessica then joined the Environmental Sciences Department at the University of Virginia in 2011, where she is currently pursuing her Ph.D. Her current research is on the food-water nexus, focusing on the intersection of fisheries and global water resources. She uses “water footprint” concepts, network analysis, and life cycle analysis with global data sets to study trade-offs between capture fisheries, aquaculture, and freshwater resources.
