Department of Evolution and Ecology, College of Biological Sciences
Evolutionary biology, invertebrate zoology
I am interested in life history evolution and the role of asexual reproduction in life history.
Science teaching, especially in Introductory Biology
I develop teaching methods to make lecture and laboratory teaching more effective in very large classes; I am interested in pairing technology with classroom experience to maximize the value of in-person instruction. I have contributed extensively to course design, lab design and lab manual creation.
Interactive on-line material for teaching animal development
I am currently developing interactive web-based teaching modules to explore the events in animal development, the mechanisms underlying development, and the value of developmental characters for phylogenetic inference.
Textbook development for Zoology
I am a member of the author team for Integrated Principles of Zoology (Hickman, Roberts, Keen, Larson, I'Anson and Eisenhour), for Animal Diversity (Hickman, Roberts, Keen, Larson, and Eisenhour), and for the associated lab manuals(Lab Manual for Integrated Principles of Zoology; Laboratory Manual for Animal Diversity, both Hickman, Kats, and Keen.) The texts are also published in Italian and Spanish.
Increasing interactivity in classroom instruction
I was part of a 5-person team from UC Davis invited to the Nara Institute of Science and Technology (March 2009) to discuss curriculum development and incorporation of interactive methods of instruction in science teaching. This followed previous work with the Summer Institute on teaching methods (HHMI and NSF-sponsored) and other related conferences.
