Robert L. Siegrist
University Emeritus Professor, Civil and Environmental Engineering
Robert L. Siegrist, Ph.D., P.E., BCEE is a University Professor Emeritus of Environmental Science and Engineering at the Colorado School of Mines (CSM). During a transitional retirement period, he is sustaining his affiliation with CSM as a Professor in the Civil and Environmental Engineering Department. From 2001 to 2010, Dr. Siegrist served as Director of the Environmental Science and Engineering Division at CSM. Dr. Siegrist earned his B.S. (High Honors) and M.S. in Civil Engineering and his Ph.D. in Environmental Engineering at the University of Wisconsin. During his career, Dr. Siegrist has held academic and research positions with the University of Wisconsin, Norwegian Institute for Georesources and Pollution Research, Oak Ridge National Laboratory, and the Colorado School of Mines. Since 1995 he has been a faculty member with the Colorado School of Mines. During his career, he has graduated 33 Ph.D. and M.S. students, developed and taught a variety of undergraduate and graduate courses, and directed interdisciplinary research projects with budgets totaling $15 million dollars. Dr. Siegrist is an internationally recognized expert in onsite water reclamation using natural systems and appropriate technology, and in situ remediation of contaminated soil and groundwater using active and passive physicochemical and coupled bioprocess technologies. He has published 300 technical papers and two reference books and holds two U.S. patents. He has also given invited talks at more than 100 workshops and conferences in the U.S. and around the world; during the past few years, he has delivered invited lectures in Australia, Norway, Denmark, Spain, Greece, Romania, Serbia, Nepal, Thailand, Vietnam, and Ireland. Dr. Siegrist has served as an expert panel member and advisor for many U.S. agencies including the U.S. Environmental Protection Agency, Department of Energy, Department of Defense, National Research Council, and Government Accountability Office, as well as for several foreign government organizations. He has been a Fellow with the NATO Committee for Challenges to Modern Society. During his career, he has received recognitions and awards for his service activities and achievements. Outside of his academic career, Dr. Siegrist has a passion for hiking, trail running, and climbing. During the past three decades with family and friends, he has pursued rock climbing and mountaineering across the U.S., Canada, Europe, South America, and Asia.
