James R. Mihelcic is the Samuel L. and Julia M. FlomEndowed professor of civil and environmental engineering at the University of South Florida. There he directs the Center for Reinventing Aging Infrastructure for Nutrient Management and an Engineering for International Development program that allows students to combine their graduate studies with international service and research in the Peace Corps (or NGO) as water/sanitation engineers (he also directs a Coverdell Fellows program for returned Peace Corps volunteers). His teaching and research interests are centered around engineering and sustainability, specifically understanding how global stressors influence water and wastewater management and provision of water, sanitation, and hygiene (WASH) in humanitarian/development situations. Dr. Mihelcic is an Associate Editor for Environmental Science and Technology and Environmental Science and Technology Letters. He served two terms as a member of the Environmental Protection Agency's Chartered Science Advisory Board, is a past president of the Association of Environmental Engineering and Science Professors (AEESP), a Board Certified Environmental Engineering Member, and past Board Trustee with the American Academy of Environmental Engineers & Scientists (AAEES). Dr. Mihelcic is lead author for two other textbooks: Fundamentals of Environmental Engineering (John Wiley & Sons, 1999) (translated into Spanish) and Field Guide in Environmental Engineering for Development Workers: Water, Sanitation, Indoor Air (ASCE Press, 2009).Dr. Julie Beth Zimmerman holds joint appointments as a professor in the department of chemical and environmental engineering and school of the environment at Yale University. She also serves at the Senior Associate Dean for Academic Affairs at the Environment School as well as the Deputy Director of Yale's Center for Green Chemistry and Green Engineering. In 2020, Dr. Zimmerman was named as the Editor in Chief of Environmental Science and Technology. Her pioneering work established the fundamental framework for her field with her seminal publications on the "Twelve Principles of Green Engineering" in 2003. She demonstrates this framework and systems-thinking in her research including breakthroughs on the integrated biorefinery, designing safer chemicals and materials, creating novel materials for water purification, and assessing potential benefits and impacts of sustainable technologies. In addition to academic pursuits, Julie has assisted many of the Fortune 100 Companies in developing innovation strategies based on the principles of sustainability, green chemistry and green engineering through her consulting company Sustainability A to Z, LLC.
