Halina Szejnwald Brown is Professor Emerita of Environmental Science and Policy at Clark University and Associate Fellow at Tellus Institute. She came to the U.S. at age 20 as a refugee from Poland. With a doctoral degree in chemistry, during the 1980s Brown was a chief toxicologist at the Massachusetts Department of Environmental Protection, advising the commissioner on the agency’s environmental health policy. Since coming to Clark in1987, Brown’s research and teaching has evolved in several directions. She published and consulted widely on new methods of risk assessment and led a pioneering study of how U.S. multinational corporations managed hazards in their facilities in India and Thailand. She conducted a study of the institutionalization of Global Reporting Initiative (GRI), a global model for civil regulation based on information disclosure.

Since 2000 the theme of Brown’s work has been the interface between technology, policy and culture in a transition to sustainable and prosperous future. Working in the U.S. and Europe, Brown has studied technological innovations systems and socio-technical transitions. In 2008 she co-founded the knowledge network Sustainable Consumption Research and Action Initiative (SCORAI) and is its board member. Brown was a visiting professor at University of Utrecht, Delft University, and Central European University; served on numerous committees of the National Academy of Sciences; and is a Fellow of the American Association for the Advancement of Science and a Fellow of the International Society for Risk Analysis.

During the 1990s Brown worked in Poland studying the relationship between air pollution and lung cancer, and the transition of the environmental and occupational regulatory system to market economy and democracy. 

Brown co-chairs Citizens’ Commission on Energy in her home town of Newton, MA. She co-authored four books: Corporate Environmentalism in a Global Economy; Effective Environmental Regulation: Lessons from Poland’s Experience; Innovations in Sustainable Consumption; and Social Change and the Coming of Post-consumer Society.

Richard (Dick) L. Raymond, Sr. is acknowledged by the US EPA as the “grandfather of in-situ bioremediation” in the United States. During the early 1970’s, while employed by the Sun Oil Company, he developed the microbial and field techniques that are now universally known as the “Raymond Process” for the cleanup of groundwater contaminated with petroleum and petroleum products, a great alternative to the endless and extensive process of “pump and treat.” His 1974 patent for “Reclamation of Hydrocarbon Contaminated Groundwater” provided the basis for the development of the groundwater bioremediation industry that is now a worldwide business. His 1984 patent, “Stimulation of Biooxidation Processes in Subterranean Formations,” developed the use of hydrogen peroxide to overcome limitations in the existing methods for mass transfer of oxygen to groundwater.

Countless books and research articles acknowledge Raymond’s seminal contributions as the inventor of process technology for the in-situ bioremediation of contaminated groundwater. While at Sun Oil Co., Mr. Raymond directed a group of microbiology specialists, and early research activities greatly expanded the scope of biological hydrocarbon oxidations.

Mr. Raymond has received numerous awards for his research over the years including the Society of Industrial Microbiologists Charles Porter Award. He also served on numerous committees including the API Groundwater Task Force, peer review panel of the Robert S. Kerr Environmental Research Laboratory, and the USEPA Valdez Oil Spill Panel. He received his B.S. and M.S. degrees in Microbiology from the University of Illinois-Champaign in 1947 and 1951, respectively. His college studies were interrupted by World War II, when he served as a B-17 navigator in the European theater. After graduation, he worked for Socony Mobil Oil Co. and Sun Oil Co. as a Research Microbiologist. After retiring from Sun Oil Co. in 1982, he founded the first in-situ bioremediation company (Biosystems, Inc.) in the US. The company was later purchased by the DuPont Company and became DuPont Environmental Remediation Services (DERS).
