From 2011-17, Russell was Director of the International Research Office of the US Army Engineer Research and Development Center. Prior to that, he served from 1993-2011 as Program Manager for Terrestrial Sciences at the Army Research Office. Russell also has worked in the Lunar Receiving Laboratory and Geochemistry Division at the NASA Manned Spacecraft Center, at the Scottish Universities Research and Reactor Center, in the UK Natural Environment Research Council and has held faculty positions at Michigan State University and Southern Methodist University. He is a Fellow of the Geological Society of America and National Speleological Society, past Chair of the Geological Society of America Division of Mineralogy, Geochemistry, Petrology, & Volcanology and a former President of the International Association of GeoChemistry. His current research interests include riverine geochemistry and laser-induced breakdown spectroscopy. Russell holds a BA from the University of Texas, MS from the Pennsylvania State University, and PhD from McMaster University.

Dr. William Berry Lyons

Dr. Lyons is a Distinguished Professor, College of Arts and Sciences, School of Earth Sciences, and Senior Research Scientist at the Byrd Polar and Climate Research Center, The Ohio State University. Lyons and his research group currently conduct research on three specific topics: 1. the biogeochemistry of Antarctic terrestrial/aquatic ecosystems and how they respond to climate change, 2. the interactions and rates of chemical weathering, erosion/sediment transport and carbon dynamics, especially in small, mountainous watersheds, and 3. the impact of urbanization, suburbanization and agricultural activities on water quality. He is a Fellow of GSA, AAAS and AGU. He has been the lead investigator of the McMurdo Dry Valleys Long Term Ecological Research program, one of the two Antarctic LTER sites funded by the National Science Foundation. Dr. Lyons is also a U.S. representative on the Geosciences Scientific Group of the Scientific Committee for Antarctic Research (SCAR), and the former Director of the School of Earth Sciences, and the Byrd Polar and Climate Research Center at OSU.

Dr. Fred L. Ogden

Dr. Ogden is presently serving as Senior Scientist and Academic-in-Residence at the U.S. National Water Center, in Tuscaloosa, Alabama, where he is helping to design next-generation hydrological models for use in water prediction by the U.S. National Weather Service.  Dr. Ogden is also on leave from the Department of Civil and Architectural Engineering at the University of Wyoming.  He is the recipient of numerous awards for research and teaching.

Dr. Ellen E. Wohl

Dr. Ellen Wohl received a BS in geology from Arizona State University in 1984 and a PhD in geosciences from the University of Arizona in 1988. She has been on the faculty in the Geosciences Department at Colorado State University since 1989 and is now a University Distinguished Professor. Her research focuses on form and process in rivers and is primarily field-based, with an emphasis on bedrock canyon rivers, mountain streams, and physical-biotic interactions in rivers. She has conducted field work on every continent except Antarctica and has authored or co-authored more than 200 peer-reviewed journal articles and 18 books or edited volumes.

Dr. David Hedley MacDonald Alderton

Dr. Alderton is an Honorary Research Associate in the Department of Earth Sciences at Royal Holloway, University of London, UK. Formerly a lecturer in Geology at Royal Holloway with over 35 years of experience teaching at undergraduate and postgraduate levels, his research using field and laboratory-based studies has been carried out at numerous locations around the globe. The results of this research have been widely published, with the focus on two broad themes: the characteristics and genesis of hydrothermal, metalliferous mineral deposits, and the geochemistry of mining-related pollution. Dr. Alderton’s collaboration with the mining and engineering industry has concentrated on the chemical and mineralogical characterization of mining waste and minimizing its effect on the environment.

Dr. Yousif K. Kharaka

Dr. Yousif Kharaka is a senior research hydrogeochemist (emeritus since, 2012) with the U.
S. Geological Survey, Menlo Park, California. As a Research Scientist at the University of California, Berkeley (1971-1995), and at USGS since 1975, he has been conducting field and laboratory geochemical investigations in the broad areas of water-gas-rock interactions in a variety of natural and contaminated systems. His current investigations cover naturally occurring organics, organic-inorganic interactions, CO2 sequestration in saline aquifers and depleted oil and gas reservoirs, remediation of contaminated agricultural drainage, environmental impacts of water produced with petroleum, and the role of fluids on the dynamics of the San Andreas Fault system.

Dr. Kharaka received his B.Sc. (honors) from Kings College, London, in 1963, and his Ph.D. from the University of California, Berkeley, in 1971. He is currently an associate editor of Applied Geochemistry. Dr. Kharaka was the Secretary General for the Seventh International Symposium on Water-Rock Interaction (1992) and was the Chairman of the Working Group on Water-Rock Interaction of International Association of GeoChemistry (IAGC) from 2001 to 2007. He was also a Member of the AAPG Global Climate Change Committee (2007-2010).

Dr. Osvaldo Arce Burgoa

A native of Bolivia, Dr. Arce Burgoa spent his childhood in the Siglo XX-Llallagua and Sala Sala-Chorolque mining camps where his father was a mining engineer for Corporación Minera de Bolivia (COMIBOL). Dr. Arce Burgoa received a degree in geological engineering from the Universidad Mayor de San Andres in La Paz, and a doctorate in economic geology and mineral processing at the Tohoku University in Sendai, Japan. His professional experience has included working for Empresa Mineral Unificada S. A. (EMUSA), most recently as Exploration Manager, and he was Executive Director of the National Geological and Mining Survey (SERGEOMIN) and technical advisor to COMIBOL. He has published 24 technical articles and a book entitled Metalliferous Ore Deposits of Bolivia (2009). He is currently a consulting geologist and works on a number of projects on several continents.

Chaired by Dr. Russell Harmon, GPI’s Technical Advisory Council provides scientific and technical guidance and oversight of existing and proposed activities and programs as requested by the Board. The TAC members are highly respected and qualified geoscientists who can address a wide variety of geologic issues in all environments.
