About Us

Dr. Reed Maxwell is an Associate Professor in the Geology and Geological Engineering Department at the Colorado School of Mines. His research interests are focused on hydrology, particularly scientific questions relating to understanding connections within the hydrologic cycle and how they relate to water quantity and quality. He teaches classes on integrated hydrology, fluid mechanics and modeling terrestrial water flow. He leads a research group of one postdoc and ten graduate students in the Integrated Groundwater Modeling Center. Before joining the faculty at Mines, Dr. Maxwell was staff in the Hydrologic Sciences group at Lawrence Livermore National Laboratory and he holds a Ph.D. degree in Environmental Water Resources from the Civil and Environmental Engineering Department at the University of California, Berkeley.

Sophia Seo is a Senior Research Associate in the Geology and Geological Engineering Department at the Colorado School of Mines. She has been with the International Ground Water Modeling Center since 1998 managing the center in its mission to stimulate the appropriate use of simulation models and related computer-based support technology in the management and protection of groundwater resources. She did extensive work in ground water modeling, involved in various software evaluations, and produced an instructional DVD, The Interactive Roles of Surface Water & Ground Water, to educate the public regarding the interaction of surface water and groundwater in conjunctive use situations.  Her research interests focus on surface water-groundwater interactions, groundwater flow and transport modeling, inverse modeling, parameter estimation, and aquatic chemistry.

Chunmiao Zheng, is currently the George Lindahl III Endowed Professor of Hydrogeology in the Department of Geological Sciences at the University of Alabama. He is also Chair Professor and Director of the Center for Water Research at Peking University in Beijing, China. The primary areas of his research are contaminant transport, groundwater management, and hydrologic modeling. He is developer of the widely used MT3DMS contaminant transport model and co-author of the textbook Applied Contaminant Transport Modeling published by Wiley in 1995 and 2002 and translated into Chinese in 2009. He is recipient of the John Hem Excellence in Science and Engineering Award from the National Ground Water Association in 1998 and a fellow of the Geological Society of America since 1999. He received the Birdsall-Dreiss Distinguished Lecturer award from the Geological Society of America in 2009 that took him to 70 universities and research institutions worldwide. He has served as associate editor for leading hydrology journals, including Water Resources Research, Ground Water, Journal of Hydrology, and Hydrogeology Journal. Currently, he is a member of the Standing Committee on Hydrologic Science of the National Research Council, and president of the International Commission on Groundwater of the International Association of Hydrologic Sciences. He received a Ph.D. in hydrogeology with a minor in civil and environmental engineering from the University of Wisconsin-Madison in 1988.

Mary Hill, PhD, is Project Chief for the U.S. Geological Survey (USGS) and a recipient of the USGS Meritorious Service Award, the ASCE Walter Huber Research Prize, and the NGWA M. King Hubbert Award. Dr. Hill was the NGWA Darcy lecurer in 2001 and Past-President of the International Commission for Ground Water. She is Adjunct Professor at the University of Colorado at Boulder and the Colorado School of Mines. She authored MODFLOWP, the popular PCG2 solver for MODFLOW, and articles on solvers, nonlinear regression, confidence intervals, and calibration methodology. She co-authored the UCODE, MODFLOW-2000, and UCODE_2005 inverse modeling codes, the OPR-PPR code for evaluation the importance of data to predictions, the MMA code for evaluating structural model uncertainty, and the Hill and Tiedeman (2007) text book published by Wiley. She is also a co-author on MOFLOW-LGR and MODPATH-LGR, for simulating groundwater flow and transport through locally refined grids. She has experience modelling saltwater intrusion, groundwater supply, stream interaction, and regional groundwater flow and transport in southern Nevada, USA. She has taught semester and short workshops for 31 years.
