Morvarid is a visiting scientist in biogeochemistry department. Morvarid’s research goal is to apply her rigorous training in chemical engineering to one of the top environmental problems of our time, nutrient pollution. She specializes in developing and testing process-based models of nutrient transformations in streams and coastal waters, which can then be used to better manage point and non-point sources of nutrients within urban and agriculturally impacted watersheds.
