Research Vision
My research combines mathematical modeling, theoretical ecology, and computational approaches to understand how aquatic ecosystems respond to environmental change across biological scales—from individual cells to global biogeochemical cycles. By integrating ecological theory with experimental observations and field data, I develop mechanistic models that reveal the processes governing biodiversity, nutrient cycling, and ecosystem resilience. My goal is to improve predictions of ecosystem responses to climate change and provide scientific insights that support the sustainable management of marine environments.
