CHRISTINE MASAE KEOLANI "LANI" BOLDT is a civil engineer with expertise in establishing, developing, and directing research and activities related to health and safety issues in underground and surface mining.  Her career included 4 years with the U.S. Forest Service, followed by 17 years with the U.S. Bureau of Mines and 11 years with the National Institute for Occupational Safety and Health (NIOSH) at the Spokane Research Laboratory, from which she retired in 2007 as Research Branch Chief.  Her experience lies in identifying issues associated with surface and underground mine engineering and mining processes that relate to workforce safety and finding effective, long-term solutions to address these potential health and safety hazards.  Specific areas in which she has worked include the use of mine waste as underground backfill and the geotechnical stability of surface mine wastes, reducing the hazards of working with large, mobile equipment (trucks and surface mine haulage equipment), and developing and quantitatively evaluating the effectiveness of self-directed team training in small work groups in sand and gravel mines.  A Certified Mine Safety Professional, Dr. Boldt also has participated in numerous federal committees related to mine and dam safety, and has received awards for her work in engineering and technology transfer with the U.S. Bureau of Mines.  She received her B.S. in civil engineering from Gonzaga University, her M.S. in engineering from Washington State University, and her Ph.D. in leadership from Gonzaga University.


MICHAEL J. CARROLL is a petroleum geologist and proven oil finder with more than 30 years of experience in the oil and gas industry.  His career began with Conoco in Oklahoma City where he had early success logging samples and identifying new drill sites. After tours of duty in offshore and onshore Louisiana and Texas with Aminoil and Louisiana Land and Exploration, he became part of an effort at British Petroleum that ventured into the Deepwater Gulf of Mexico, working in areas of Mississippi Canyon, Viosca Knoll, and Atwater Valley. He worked as the lead stratigraphic explorationist prior to the drilling of the first well at the Mars discovery. He was the initial British Petroleum geologist on both the Ursa and Europa projects.In 1993 he formed Principle Energy Development, LLC and began consulting and putting together oil and gas ventures as an independent. During this time period he was involved with projects in Ghana, Senegal, and Benin. This phase of his career continued until 2001 where he served as Exploration Manager for Louisiana Delta Oil, LLC. In 2004 he became an exploration geologist with Hunt Oil in Dallas where he successfully made several discoveries in the Lower Wilcox. In 1981 he became the first president of the National Association of Black Geologists and Geophysicists and remains very active in the organization. A native of Richmond, Virginia, he graduated with honors from Virginia State College with his bachelor’s degree. He then studied carbonate geology in northeastern Mexico and subsequently attended the University of New Orleans where he became the first African-American graduate of their master’s degree program in petroleum geology.

DOROTHY J. MERRITTS is a geologist with expertise in streams, rivers, and other landforms, and on the impact of humans and geologic hazards on landscape evolution.  In the western United States, she conducted pioneering research on the San Andreas Fault of coastal California, and her international work focuses on fault movements in South Korea, Indonesia, Australia, and Costa Rica. Her primary research in the eastern United States is in the Appalachian Piedmont, particularly in Pennsylvania and Maryland, where she is investigating the role of human activities in transforming the valley bottom landscapes of eastern North America since European settlement.  She is a professor in the Department of Earth and Environment at Franklin Marshall College in Lancaster, Pennsylvania.  In 2011-12 she was Allen Cox Visiting Professor at Stanford University, California, and in 2004-2005 she was the Flora Stone Mather Visiting Distinguished Professor at Case Western Reserve University in Cleveland, Ohio.  She was chair of the 2008-10 National Research Council Committee on Challenges and Opportunities in Earth Surface Processes and served on the Steering Committee for the National Center for Airborne Laser Mapping. She was the co-recipient (with Robert Walter) of the 2011 Kirk Bryan Award for outstanding research from the Geological Society of America. She is author of two textbooks on environmental geosciences, author or co-author on more than 60 scientific articles, and the editor and contributing writer for numerous scientific books. She received her B.Sc. from Indiana University of Pennsylvania, her M.Sc. from Stanford University, and her Ph.D. from the University of Arizona.

JEROME C. MUYS, JR. practices law with Sullivan & Worcester LLP where he is partner.  He joined the firm after approximately 25 years with the office of Swidler and Berlin.  Prior to entering private practice, Mr. Muys served as a staff attorney in Land and Natural Resources Division of the United States Department of Justice in Washington, D.C., which involved enforcement litigation under the full range of environmental statutes administered by the U.S. Environmental Protection Agency (EPA).  From 1978-1985, following graduation from law school, he served as a staff attorney in the Office of Enforcement at EPA Headquarters, principally as a member of the EPA’s Hazardous Waste Enforcement Task Force.  Mr. Muys’ practice historically has focused on regulation of hazardous waste, air, water, groundwater and related environmental protection proceedings before the EPA, the federal courts and state administrative agencies, including representation of companies and trade associations in the energy, automotive and consumer products sectors.  More recently, Mr. Muys’ practice has expanded to include renewable energy project development, with particular attention to the environmental requirements applicable to same.  He received his A.B. in political science from the University of North Carolina, and his Juris Doctor and LL.M (Taxation) from George Washington University.

JOEL L. RENNER has spent much of his career working with geothermal energy. He began his career with the U. S. Geological Survey (USGS) in 1970 and evaluated geothermal resources, saline minerals deposits and coal resources.  He participated in several USGS assessments of the geothermal resources of the United States and was also the lead geologist for the initial Department of Interior geothermal lease sales.  He was the geothermal lead at the U. S. Department of Energy’s Idaho National Laboratory (INL) from 1986 until his retirement in early 2008.  At the INL he led a multi-disciplined group studying reservoir engineering, tracer interpretation, and conversion of geothermal-energy to electricity.  He led reviews of geothermal potential throughout the United States, Africa, the Caribbean and Indonesia.  Mr. Renner has also conducted coal studies, oil and gas evaluations, and investigated both industrial minerals and metal ore deposits while employed by Gruy Petroleum Technology and Ernest K. Lehman and Associates, a mineral exploration and evaluation consultancy.  Since retiring from the INL he has provided technical expertise on geothermal resources and exploration programs to U. S and international government and private clients.  He was a co-convener of the Exploration Working Group of the International Partnership for Geothermal Technology.  He is a member of the U. S Geothermal Energy Association’s Scientific and Technical Advisory Committee, the Geothermal Resources Council, the International Geothermal Association and the American Geophysical Union.  He received his bachelor’s degree in mathematics from Carleton College and his master’s degree in geology from the University of Minnesota.
