Educational Background

B.S. in Biology (Honors), 1991, University of California at Riverside
M.S. in Biology, 1993, University of Michigan, Ann Arbor

Research Interests

I infer the phylogenetic (evolutionary) relationships of freshwater fishes using DNA sequences and to a lesser extent morphology. Presently I am studying the evolutionary relationships and phylogeography of the goodeids of the Mesa Central of Mexico. At a broader level, my interests include biogeography, the factors affecting the species richness of groups (speciation and extinction), and the documentation and conservation of fish diversity.
