Research Interests


In July 2014, I will be starting as an Assistant Professor of Vertebrate Biology at Wabash College.


My work is centered around evolutionary ecology in a community context, using primarily larval amphibians and pond ecosystems.  I'm presently focused on studying the causes and consequences of intraspecific genetic and phenotypic variation in ecologically relevant traits, both among and within populations and through time. 

I'm interested in the role of spatially heterogeneous selection in producing interpopulation variation (i.e. local adaptation) and the impacts of such evolution on ecological processes.  Variation among populations is becoming increasingly apparent in studies of wild organisms and may have profound consequences for communities and ecosystems.  I'm also interested in variation among individuals within populations in spite of (or because of) selective forces.  The diversity present in some populations can be dramatic and influential at broad ecological scales, as highlighted by the sub-discipline of community genetics.  I seek to understand both the origins of such diversity (focusing in particular on the role of species diversity and interspecific interactions) and its impacts on the community, distinguishing the effects of individual genotypes/phenotypes and varying levels of diversity.  Understanding the patterns and pace of how such populations change through time is also important, as research in eco-evolutionary dynamics reveals how evolutionary and ecological processes can act on similar time scales and feedback upon each other.

Evolution is garnering great interest as an ecological force, particularly as anthropogenic change results in evolutionary responses.  Furthermore, diversity is being eroded in wild populations at multiple scales, including genetic and species diversity, with limited understanding of the relationships between these levels of diversity and between diversity and ecosystem processes.  While not explicitly application-oriented, my work attempts to inform these growing concerns from a theoretical perspective.
