He has appointments in the School of Forestry and Environmental Studies, Department of Chemistry, and Department of Chemical Engineering. In addition, Prof. Anastas serves as the Director of the Center for Green Chemistry and Green Engineering at Yale. Anastas served as the Assistant Administrator for the US Environmental Protection Agency and the Agency Science Advisor from 2009-2012. From 2004 -2006, Prof. Paul Anastas served as Director of the ACS Green Chemistry Institute in Washington, D.C. He was previously the Assistant Director for the Environment in the White House Office of Science and Technology Policy where he worked from 1999-2004. Trained as a synthetic organic chemist, Dr. Anastas received his Ph.D. from Brandeis University and worked as an industrial consultant. He is credited with establishing the field of green chemistry during his time working for the U.S. Environmental Protection Agency as the Chief of the Industrial Chemistry Branch and as the Director of the U.S. Green Chemistry Program. Dr. Anastas has published widely on topics of science through sustainability including eleven books, such as Benign by Design, Designing Safer Polymers, Green Engineering, and his seminal work with co-author John Warner, Green Chemistry: Theory and Practice.

Dr. John C. Warner is one of the founders of Green Chemistry. He co-authored the seminal book Green Chemistry: Theory and Practice, which first described the ’Twelve Principles of Green Chemistry.’ In 2009, the Council of Scientific Society Presidents honored Dr. Warner with the Leadership in Science Award for founding the field of Green Chemistry. Dr. Warner is President, Chief Technology Officer, and Chairman of the Board of the Warner Babcock Institute for Green Chemistry, which he founded with Jim Babcock in 2007. Dr. Warner worked at the Polaroid Corporation from 1988-1997 in exploratory research and media research. In 1997 he accepted a position in the Chemistry Department at the University of Massachusetts-Boston, where he started the world's first Green Chemistry Ph.D. program. Following this, he founded the Center for Green Chemistry as a professor at University of Massachusetts-Lowell. John received the American Institute of Chemistry's Northeast Division's Distinguished Chemist of the Year for 2002, and the 2004 Presidential Award for Excellence in Science Mentoring. Dr. Warner currently serves on the Board of Directors of the Green Chemistry Institute in Washington, DC and on the Science Advisory Board of Strategic Environmental Research and Development Program, the Department of Defense's environmental science and technology program. Dr. Warner is editor of Green Chemistry Letters and Reviews, and associate editor of the journal Organic Preparations and Procedures International. John has been awarded a number of patents in the fields of semiconductor design, biodegradable plastics, personal care products, and polymeric photoresists. This year, Dr. John C. Warner has been awarded the 2014 Perkin Medal by the Society of Chemical Industry, the highest honor in American applied chemistry.
