Steve Chapra is Professor Emeritus and Louis Berger Chair in Environmental Engineering at Tufts. He received his PhD in Environmental Engineering from the University of Michigan and has published over 200 technical publications including 11 textbooks. Steve’s research focuses on understanding and protecting the water-quality of rivers, lakes, estuaries, and oceans. Over his 50-year career, he has travelled extensively studying many of the world’s great waterways. He has special interest in how engineering, science, and computer modeling can be employed to reduce water-quality problems in a sustainable and cost-effective fashion. On this trip, he will present several lectures including his own research on the history of water quality, how climate will profoundly influence the world’s future water quality, and a close look at the Mediterranean Sea from the perspective of an environmental scientist/engineer.
