Keywords: Lower foodweb dynamics of aquatic ecosystems; resource competition; succession; nonlinear dynamics; freshwater inflows

Interests:
Research in my lab focuses on lower foodweb dynamics of aquatic ecosystems with emphasis on interactions between biotic processes and the physicochemical environment, non-linear population dynamics arising from competition, and application of ecological theory towards better management of our natural resources. My research approach encompasses field sampling and experimentation, use of laboratory microcosms, and numerical modeling. My field research includes both inland and coastal systems, lentic and lotic envornments, and takes place in Texas, Venezuela, and Israel.
