Welcome to the Peña Lab!

Our research aims to advance mechanistic knowledge of contaminant, nutrient, and carbon transformations in natural and engineered systems

Our Research

We take an interdisciplinary approach to environmental and molecular biogeochemistry. Our projects include the effects of global warming on carbon cycling, manganese and iron redox chemistry, and impacts of wildfires on water quality and soil processes
