Dr. Ehsan Vahidi is an interdisciplinary researcher who has crossed traditional boundaries between metallurgical engineering and sustainability sciences. His research takes fundamental environmental engineering and translates this into applied settings, primarily in the mining and metallurgical industries. Dr. Vahidi received his B.Sc. and M.Sc. degrees in Materials and Metallurgical Engineering from Sharif University of Technology and the University of Tehran, respectively. After earning his second master’s degree in Environmental Engineering from the University of South Florida, he obtained his Ph.D. from Purdue University in Environmental & Ecological Engineering. Prior to joining UNR as an Assistant Professor in 2020, Dr. Vahidi was a Postdoctoral Associate at Massachusetts Institute of Technology.
