Research

I am a natural history enthusiast with diverse interests in organismal, evolutionary, and conservation biology. I’m especially interested in patterns of phylogeny, phenotypic divergence, and the relationship between them. How is it that some closely-related species are very different whereas some distantly-related species look very similar? Most of my projects involve birds, including using DNA sequences to infer evolutionary relationships among species, measurement of plumage color patterns to study their evolution and adaptive significance, and field surveys of declining grassland birds and the Regal Fritillary butterfly to study effects of prairie burning and grazing on their abundance. More recently, I’ve also been using natural selection as a tool to domesticate microbes for use in biotechnology and to study evolution experimentally.

 

Interested in doing research with me?

Talk with me if your research interests fit with mine. I’d be particularly happy to advise graduate students or to work with undergraduates interested in the following:

 

  • ecological or conservation questions investigated through field surveys (especially of birds, amphibians, reptiles, or butterflies).

 

  • phylogenetic, biogeographic, or comparative evolutionary questions investigated using DNA marker, locality, or morphometric evidence from specimens in the field or museum collections.

 

  • evolutionary, growth/developmental, “behavioral”, or ecological questions investigated through experimental evolution of microbes (e.g. of bacteria, yeast, or as in my on-going work, of filamentous fungi).

 

I encourage students to give a lot of thought to what theoretical issues they can address. However, I find novel descriptive natural history studies very compelling and I would be happy to work with students who have clear ideas about what they wish to investigate. Finally, if you have ideas and interest in doing work that overlaps with science education or philosophy of science, let’s talk!

 

Teaching

Courses that I’m currently or have recently been responsible for at ESU include EB 480: Principles of Ecology, ZO 530: Animal Behavior, and ZO 200–201: Intro. Anatomy & Physiology (lecture and lab). In fall 2016 will be co-teaching CW 101: Freshman Seminar. In spring 2017, I hope to offer ZO 459/859: Herpetology (with lab).
