Dr. Teresa (Terri) G. Bowers (BS Geology and Mathematics 1977), Principle, Gradient Corporation Teresa S. Bowers, Ph.D. is a Principal at Gradient Corporation, an environmental consulting firm in Cambridge, Massachusetts, with a national practice in risk assessment and contaminant fate and transport issues.Dr. Bowers received B.S. degrees in Mathematics and Geology from Purdue University in 1977 and a Ph.D. in geochemistry from the University of California, Berkeley in 1982. She completed post-doctoral work in the Department of Geological and Planetary Sciences at Caltech, and then moved to the Boston area in 1985, spending one year as a Visiting Professor at Harvard University and five years in Earth and Atmospheric Sciences at M.I.T. where she held several positions, including Crosby Lecturer in Resource Geology.In 1990, Dr. Bowers moved to Gradient Corporation, where she began specializing in modeling human exposure to environmental contaminants, with emphasis on modeling health effects resulting from exposure to environmental sources of lead, arsenic, and other metals, and application of this information to the calculation and negotiation of site-specific cleanup levels. She has done extensive work with U.S. EPA’s Integrated Exposure Uptake Biokinetic (IEUBK) model for lead, and developed an adult lead model that is currently recommended by the U.S. EPA for establishing cleanup levels for lead at industrial/commercial sites. Additionally, she has worked on several river sediment systems involving PCB contamination, where she has developed unique statistical methodologies to calculate risk-based cleanup levels. She was the lead risk assessor involved in assessing risks to human health resulting from spraying pesticides in the New York City area in 1999 and 2000 as a control for mosquitoes bearing the West Nile Virus. She is frequently invited to participate in EPA workshops, has been a member of National Academy of Science Review Panels, and is currently a member of the advisory council for the National Insitute of Environmental Health and Safety (one of the NIH institutes).Dr. Bowers is the author of more than 40 journal articles on geochemistry, risk assessment, soil cleanup levels, and other topics, including a urine arsenic multi-pathway exposure model, an aggregate pesticide exposure model, and a statistical assessment of lead exposure and IQ data, soon to be published in Neurotoxicolgy.In 1999, Dr. Bowers together with two business partners, participated in a management buyout of Gradient Corporation, which prior to that time was a subsidiary of the IT Group. Today, Gradient remains under private ownership with a staff of 60 who focus on interpretation of environmental data, providing consulting services to major industry, city governments, and numerous law firms.<back to top> |

Mr. Paul P. Krishna (MS Geology 1988), Environmental Manager, ExxonMobil Corporation Paul P. Krishna earned a Bachelor of Science degree in Geology from the University of Delaware in 1986. He received a Masters of Science degree from Purdue University Earth & Atmospheric Science (EAS) Department in 1988. He completed a curriculum that was largely Geoscience with additional courses in Geophysics and Environmental Science. He completed a thesis on sedimentology, stratigraphy, and paleoecology of the Tres Montes Region in Chile. His panel of advisors consisted of Dr. William Zinsmeister, Dr. Donald Levandowski, and Dr. Henry Meyer.Paul is in his 18th year with Exxon Mobil Corporation and his career has involved broad exposure to many parts of the company. Paul's career began as a summer intern with Mobil Exploration & Production's Oklahoma City office in 1988. After graduating from Purdue, Paul returned to Oklahoma City with Mobil and worked as an Exploration Geologist and Production Geologist from 1989 to 1992. Paul moved to Mobil's Houston office where he was an Environmental Engineer that supported Mobil's Southern Louisiana coastal properties. In 1996, Mr. Krishna was asked to lead a company taskforce that found innovative ways to redesign work processes involved in oil and gas production. Mr. Krishna returned to Houston in 1997 and became the Quality Leader for Mobil's Onshore Gas Business Unit.In 1998-1999, Paul became the Planning Advisor to Mobil's Rocky Mountain Business Unit. In 2000, with the merger of Exxon and Mobil, Paul relocated to Fairfax, VA and supported the company's Downstream and Chemical businesses. He performed company safety, health, and environmental assessments in the Americas and Europe.

Mr. William R. Landwer (MS Geophysics 1977), President/CEO, Landex Prospecting Company Mr. Landwer is an explorationist with educational background in Geology, Geophysics, and Business. He obtained a BA in Geology at WMU in 1974, an MS in Geophysics at Purdue in 1977, and an MBA at OCU in 1983. Since 1985, Mr. Landwer (Bill) has practiced subsurface exploration consulting, geophysical data processing, prospect generation, and drilling venture business development primarily throughout the Southwestern U.S. including Oklahoma, Texas, Louisiana, and Mississippi. His most recent business venture development generates G & G venture capital funding through the LXH, L t d. Private Offering Memorandum. This effort uniquely matches exploration risk with profit incentives for private investment funding of the capital intensive exploration enterprise.
