Dr. Daigger is currently Professor of Engineering Practice at the University of Michigan and President and Founder of One Water Solutions, LLC, a water engineering and innovation firm. He previously served as Senior Vice President and Chief Technology Officer for CH2M HILL where he was employed for 35 years, as well as Professor and Chair of Environmental Systems Engineering at Clemson University. Actively engaged in the water profession through major projects, and as author or co-author of more than 100 technical papers, four books, and several technical manuals, he contributes to significantly advance practice within the water profession. Deeply involved in professional activities, he is currently Immediate Past President of the International Water Association (IWA). The recipient of numerous awards, including the Kappe, Freese, and Feng lectures and the Harrison Prescott Eddy, Morgan, and the Gascoigne Awards, he is a Distinguished Member of the American Society of Civil Engineers (ASCE), a Distinguished Fellow of IWA, and a Fellow of the Water Environment Federation (WEF). A member of a number of professional societies, Dr. Daigger is also a member of the U.S. National Academy of Engineers.
Daigger’s research has focused on the fundamental science and engineering supporting the advancement of technologies and practices which have been transformational for environmental engineering. These have included topics such as wastewater nutrient removal and recovery (biological and chemical), treatment process optimization and control (particularly biological treatment systems), control of activated sludge bulking and foaming, which can be debilitating and lead to excessive treatment costs if not properly addressed, and the highly efficient coupled attached and suspended growth systems.
