Research Interests

My research interests include disturbance and recovery dynamics in coastal and estuarine ecosystems, biodiversity prioritization to inform ecosystem management, statistical modeling including the identification of multiple stressor interaction effects, marine spatial planning, ecosystem services frameworks and climate change impacts on marine systems. My primary research focuses on the recovery of marine benthic communities from disturbance and potential interaction effects of multiple stressors. I have approached these specific research areas using a combination of models and field studies to predict community resilience to disturbance and multiple stressors. This knowledge provides the required biophysical science to quantify stressor ’footprints’, determine ecological responses of ecosystems to multiple stressors and identify ‘tipping points’ that transform ecosystems into non-desirable states. Increasingly research of stressor footprints and multiple stressor effects will be required to provide the empirical underpinnings for effective marine spatial planning.
