Dr. Jessica Ray (she/her/hers) is the Robert and Irene Sylvester assistant professor in the Department of Civil & Environmental Engineering at the University of Washington. Ray joined the University of Washington in January 2019. Previously, 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. This research was part of the NSF Reinventing the Nation's Urban Water Infrastructure (ReNUWIt) engineering research center at Berkeley. Dr. Ray received her B.S. degree in Chemical Engineering from Washington University in St. Louis in 2009. Upon graduation, Ray remained at Washington University in St. Louis to obtain a M.S. degree (2010, funded by the NSF GK-12 Graduate Research Fellowship) and a Ph.D. in Energy, Environmental Engineering & Chemical Engineering (2015, funded by the EPA Students to Achieve Results (STAR) Fellowship). During her Ph.D., Ray employed surface chemistry techniques to investigate interfacial reactions of nanomaterials in water. At the University of Washington, Ray's research program utilizes a multidisciplinary platform that bridges materials science, and environmental and surface chemistry to increase urban water supply sustainability. 


  • Ph.D. in Energy, Environmental & Chemical Engineering, Washington University in St. Louis, 2015
  • M.S. in Energy, Environmental & Chemical Engineering, Washington University in St. Louis, 2010
  • B.S. in Chemical Engineering, Washington University in St. Louis, 2009

Previous appointments

  • Miller Institute for Basic Research, Postdoctoral Fellow, University of California, Berkeley, 2015-2018

Research Statement

Ray is developing, characterizing and applying new composite materials for selective contaminant removal in water, for enhanced degradation of persistent contaminants, and for recovery of valuable species in waste streams. We explore structure-function relationships and survey physicochemical properties during synthesis and application of novel composites to understand their capabilities under conditions representative of real water sources and waste streams. Currently, our group is creating low-cost, engineered media to remove and/or degrade contaminants in urban stormwater. We are also generating functionalized composite materials to target and destroy persistent organic compounds such as per- and polyfluoroalkyl substances (PFAS).

Ray is committed to nurturing an inclusive, diverse and anti-racist environment within her research group and within the department. Ray served on the department Justice, Equity, Diversity and Inclusion faculty committee from 2019 - 2021 and worked with colleagues to institute the first faculty diversity training. In 2020, Ray's group launched an anti-racism book club for group members to grow and learn together. So far, we have read books relating to environmental racism, race relations in contemporary America, and color-blind racism. Currently, Ray is collaborating with Black, Environmental Engineering assistant professors across multiple institutions to create a guidance framework for Environmental Engineering departments to support and retain Black faculty.
