I recently joined FIU as a Professor in the Department of Biological Sciences and Director of the Southeastern Environmental Research Center.

My research interests include aquatic ecology, predator-prey interactions, food web ecology and most recently, urban stream ecology.  As Co-PI of the Luquillo Puerto Rico LTER, I have spent the last 25 years looking at energy flow between the riparian zone the streams draining the rainforest.  Other projects include the role of introduced fish on native fish communities in western US lakes and the role of urbanization on sustainable freshwater resources.
