Erwan’s Global Environmental Change Lab brings together high school and undergraduate interns, graduate students, and early career researchers to conduct interdisciplinary research aimed at understanding the drivers and consequences of global environmental change. They develop and apply a range of approaches—including process-based modeling, empirical and statistical methods, and the analysis of large observational datasets—to examine the interactions between human and Earth systems.

Their research spans both terrestrial and marine systems, with four major areas of focus:

1. The biosphere, including agriculture, forestry, biodiversity, wildfires, and ocean biological and biogeochemical systems;
2. Climate, air quality, and human health, including the compounding effects of heat, smoke, and pollution;
3. Global and regional biogeochemical cycles, including carbon, nitrogen, and mercury cycling in land, atmosphere, and ocean systems; and
4. Risk, resilience, and adaptation, identifying the key stressors and pathways that inform actionable strategies for communities, ecosystems, and economies.

Their goal is to advance understanding of how environmental stressors affect society and ecosystems and to translate that knowledge into actionable insights that support equitable, effective, and sustainable adaptation strategies. By integrating human and natural system dynamics, they aim to inform decisions that foster resilience and prosperity in a rapidly changing world.
