Biography

Dr. Jessica Ray joined the University of Washington Department of Civil & Environmental Engineering as an Assistant Professor in January 2019. Previously, Dr. Ray was a Miller Institute Postdoctoral Fellow at the University of California, Berkeley investigating low-cost engineered adsorbents for removal of trace contaminants in urban stormwater. Jessica received her B.S. (Chemical Engineering, 2009) and Ph.D. (Energy, Environmental and Chemical Engineering, 2015) from Washington University in St. Louis. As a graduate student, Dr. Ray’s research examined nanomaterial fate and transport by employing advanced surface chemistry analytical techniques for which she received the Environmental Protection Agency Students to Achieve Results (STAR) Graduate Fellowship to support her research. At the University of Washington, Jessica plans to design, characterize and apply low-cost composites (e.g., adsorbents, functionalized polymers, modified membranes) for selective removal of contaminants in stormwater and wastewater. In the future, Dr. Ray plans to expand the portfolio of composites to investigate ways to recover nutrients and other valuable materials from wastes.

Research Statement

Jessica’s research interests include functionalized composites, surface chemistry, and targeted removal and recovery of wastewater constituents. Dr. Ray is interested in a holistic and fundamental understanding of mechanisms governing composite performance from conceptualization to application, as well as ways to incorporate these new composite materials into existing wastewater treatment infrastructure. Current research projects include selective removal and destructive treatment of recalcitrant perfluoralkyl substances from groundwater, and design of inexpensive engineered geomedia for urban stormwater contaminant removal during aquifer recharge.
