Research interest:
Over the course of my career, I have pursued various research topics, ranging from aquatic toxicology, to landscape ecology, to theoretical ecology, and environmental policy. Frequently, I have approached problems by the use of computer simulation modeling and a risk assessment framework. I have always sought to apply ecological theory in the solution of practical environmental problems. Currently, my research focuses on the water-energy nexus, with specific attention to (1) water use in the production of electricity; (2) the metapopulation dynamics and conservation of freshwater mussels; and (3) risk-based decision analysis for the management of cyanobacterial blooms.
