William P. Johnson教授简介

Dr. William P. Johnson

Professor of Geology & Geophysics

Dr. William P. Johnson is an environmental engineer and geoscientist who examines the transport and fate of contaminants in the environment with a focus on predicting particle transport in porous media (e.g. pathogens and particle-borne contaminants).  He is a Professor in the Department of Geology & Geophysics\.  He was a post-doc in the Department of Chemical & Environmental Engineering U. of Arizona following his PhD in Civil Engineering (U. of Colorado), M.S. and B.S. in Geology from Dartmouth College and Whitman College, respectively.  He has been principal investigator on more than fifteen federally funded research grants (predominantly National Science Foundation and Environmental Protection Agency), and has led more than ten state-funded projects examining the fate and transport of trace elements (particularly selenium and mercury) in the Great Salt Lake and surrounding wetlands and extending to the tar sands of eastern Utah and the Gold King Mine spill of the Four Corners area.  Dr. Johnson has produced more than 100 peer reviewed publications in top-tier journals, with over 5000 citations of this work to date.
