Summary Statement of Research Interests
Understanding evolution is fundamental to deciphering the complexity of our living world and its enormous biological diversity. Wetzer is interested in evolutionary questions about invertebrates and uses phylogenetic inference to investigate broad evolutionary patterns at a macroevolutionary scale. Her specialty is Crustacea with a focus on marine isopods (pill bugs). Her extensive field work, as well as morphological and molecular systematic work in the lab reconstruct the history of character change on a phylogeny enabling evaluation of specific hypotheses and the formulation of new biologically interesting questions. Wetzer’s interests include exploring evolutionary hypotheses involving previously unexplained life history traits, homoplastic morphological features, and biogeographic distributions.

Other Advisement or Time Devoted to Students
- Work Study Students: Since 2004 created and managed ongoing program for work study students in collections care (over 35 students to date), two of whom are now permanent NHM collections staff.
See: http://research.nhm.org/mbc/students and http://isopods.nhm.org/people/
- Undergraduate Directed Research Students: Since 2004 guided 8 undergraduate
projects (USC course BISC 490, HP 290). Products have included peer-reviewed
publications, species descriptions, biological model system developement, and conference presentations.
- Postdoctoral Advisee Alexandra Hiller, Department of Animal Ecology, Justus-Liebig-
University, Giessen, Germany, contributed to the gene sequencing effort on the NSF
sphaeromatid isopod project.
