| RESEARCH:
|
My primary research interests are population genetics and ecotoxicology
of fishes. My dissertation project is a combination of field and
laboratory experiments to assess the effects of polycyclic aromatic hydrocarbons
(PAH) on DNA. Most of this research
is conducted with brown bullhead catfish in order to determine a reliable
biomarker for DNA damage, which may provide an early indicator of tumor
formation in fish exposed to PAH contaminants.
This research may potentially be used for remediation efforts in the
Grand Calumet Region of Indiana. While
at Purdue University, I have also assessed genetic variation in hatchery stocks
maintained by the Indiana Department of Natural Resources.
I examined both Skamania steelhead and London strain rainbow trout for
genetic variation at allozyme loci. My
previous research includes using genetic techniques to determine hybridization
in tilapia, minnow, and trout species, heterozygosity and fitness of mottled
sculpin, and effects of pesticides on amphibians.

| TEACHING:
|
My teaching interests are in the fields of ecology, genetics, and fish
biology. I have been responsible
for teaching laboratory sections of classes in: General Biology, Diversity of
Life, Genetics and Evolution, General Ecology, Developmental Biology, Biology
and Management of Fish, Conservation and Population Genetics, Systematics and
Ecology of Fish, and Systematics and Ecology of Amphibians. |
