Amirbahman, Aria


Aria has been a professor at Santa Clara University since January 2020. Since 2022, he has been the Department Chairperson and the Sukhmander Singh Endowed Professor. He started his academic career at the University of Maine in 1997. Prior to that, he was a postdoctoral research fellow at the Swiss Federal Institute of Environmental Science and Technology (EAWAG). He teaches courses in environmental and hydraulic engineering at SCU. His research interests are aquatic chemistry, contaminant transport, and water treatment. He studies the cycling of metals and nutrients in natural and engineered systems. Aria has been a visiting professor at the Swiss Federal Institute of Technology (ETH-Zürich), and the U.S. Geological Survey, Menlo Park, CA. He is currently conducting research on mercury biogeochemistry at the USGS. He is a registered Professional Engineer in California and has several years of professional experience as an environmental and water resources engineer in the public and private sectors.
