Current Lead Scientist

Dr. John Callaway, an internationally recognized expert in wetland restoration, specifically wetland plant ecology and sediment dynamics, was unanimously appointed by the Council as lead scientist at its July 2017 meeting. Most recently, Dr. Callaway has served as the director of the Master’s Program in Environmental Management at the University of San Francisco. “I look forward to the continuing efforts of building a collaborative scientific community with its search for common truths on the many critical issues that face the Delta,” Dr. Callaway said. “The development of One Delta, One Science is clearly a project of critical importance to California that is helping set standards of how the best available science can more effectively inform the making of policy.”
