Research interests:

I am a marine ecologist focused on understanding the impacts of current global changes on biodiversity and ecosystem functioning. My research employs both experimental and modeling approaches to address ecological questions. I conduct mesocosm experiments to investigate how climate change alters ecological interactions and I use ecosystem modeling to examine the impacts of human activities (e.g. fisheries) on food webs.
