Research Projects: http://bio.slu.edu/mayden/research.html

Courses in 2001-2006: Aquatic Ecology, Phylogenetic Systematics, Scientific Communications Other Courses: Biodiversity for Non-Scientists, Biogeography, Bioinformatics, Biology of Fishes, Current Topics in Ecology, Evolution, and Systematics, Evolution, Mammalogy, Ornithology, Principles of Biology, Species and Speciation, Vertebrate Zoology

Research interests: I maintain an active research laboratory involving undergraduate, graduate students and postdoctoral researchers studying the systematics, ecology, and biogeography of freshwater fish species. In addition to North America, my research is focused on species and ecosystems in southeast Asia, Chile, Kazakstan, Russia, Turkmenistan, and Mexico. I also oversee the Cypriniformes Tree of Life International Collaborative research initiative that involves scientists from around the world. Visit www.cypriniformes.org to learn more. Along with numerous collaborators in the USA and Mexico I am involved with a large-scale and long-term study of Mexican trout species and the aquatic biodiversity of the northwestern Sierra Madre Occidental of Mexico. For more information on this long-term project visit either www.americanfishes.com or www.utexas.edu/tmm/tnhc/fish/research/truchas_mexicanas.


Research opportunities: With an active research laboratory I usually can provide research interns for two to three undergraduate students over the course of an academic year. I am also interested in working with new graduate students and postdoctoral researchers that share my general research interests. Please stop in or contact me by email for opportunities.
