Research Focus

In my lab, we conduct broad and applied ecological research focused on the conservation of marine and estuarine ecosystems. Specifically, we seek to identify the effects of anthropogenic stressors on coastal ecosystems using field-oriented and experimental approaches. My research program focuses on question-driven research and, as such, I seek organisms/systems providing novel ecological insight rather than focusing on organism-specific hypotheses. The ultimate objective of our research is to gain a fundamental understanding of the ecological processes structuring natural ecosystems, particularly how anthropogenic perturbations have modified these processes, with a specific emphasis on the continued conservation of coastal ecosystems in the Gulf of Mexico.
