Dr. Harrel's research interests includes the ecology of freshwater and estuarine macroinvertebrates, the biomonitoring of toxic substances in aquatic environments, and the ecological succession of oxbow lakes.

The outstanding teaching and research career of Dr. Harrel has netted him several prestigious awards. He was recently named the 2003 Distinguished Faculty Lecturer. He will give a talk entitled "Environmental History of the Lower Neches River: From Clean to Polluted to Recovering" on October 20, 2003, in the University Theatre.
