Teaching Philosophy

The classroom experience is most effective when all of the students are comfortable enough to participate. The diverse and varied backgrounds of our students contribute to alternative means of addressing issues, such that one view is only the beginning.

Research Interests

  • Ecology, evolution and population structure in lower vertebrates
  • Analysis of reproductive strategies in fish and reptiles

Advised Student Research

  • Substrate preference in fishes and habitat diversity in the Mill Stream
  • Mating systems in Poecilia reticulata
  • Defense mechanisms in native Crayfish
