My teaching philosophy is founded on a passion for the sciences that has developed over a lifetime of interest in biology, research, and education. I believe that effective educators should both provide specific topical information as well as cultivate a desire to internalize overarching core biological concepts. I believe that a combination of traditional class lecture with experiential learning can unify theoretical concepts with practical application to promote a balance in student learning. I consider involvement in faculty research programs, internships, professional societies, and classroom working groups to be an integral part of enhancing subject understanding and professional development.

Some of the courses that I teach include Ecology, Biology of Food, Health and Disease, Cells and Genes, Organisms and Ecosystems, Invertebrate Zoology, Ichthyology, and Independent Studies.


Research Statement

My research interests focus on the ecology and evolution of freshwater fishes and gastropods as well as restoration and conservation of wetlands. I am particularly interested in understanding patterns of abundance (both spatial and temporal), morphology, ecological niche, as well as how wetland habitats contribute to biodiversity and ecosystem conservation. The primary mission of my lab is to promote the conservation of aquatic resources through increased understanding of the taxa and processes contained therein.

Much of my research revolves around the long term analysis of Ohio River Basin fish and gastropod assemblages. These assemblage studies have detailed population and community changes at both the taxonomic and functional level over the past century - primarily as a result of habitat alterations. Other projects branching from this theme include life history studies of large river fish diets and growth determinants.

In addition to exploring spatial and temporal patterns in aquatic assemblages, my research also includes conservation and restoration of wetland habitats. This work is particularly focused on how wetlands can contribute to nutrient reductions and improvements in water quality around the midwest.  

Some of the field and analytical methods utilized in my research include various sampling techniques (e.g. electrofishing, seine netting), geographic information systems, stable isotope analysis, UV/VIS spectrophotometry, multi-metric biological and habitat measurement procedures, geometric morphometrics, multivariate statistics, phylogenetic comparative methods, and ecological niche models.

Students interested in research involvement should contact directly regarding lab openings and potential projects.
