RESEARCH INTERESTS

My interest in aquatic ecology pertains to understanding processes affecting community structure.  For example, how chemical cues contribute to benthic patchiness or how stable isotope values change over several hundred km of a river and the implications for food web construction.  Impacts of dam operations and river regulation are another area of interest with an emphasis on the Colorado River drainage.
