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 engineered adsorbents for selective removal of contaminants in
stormwater and wastewater. In the future, Dr. Ray plans to expand the portfolio
of composite adsorbents to investigate ways to recover nutrients and other
valuable materials from wastewater.
- 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
- Miller Institute for Basic Research, Postdoctoral Fellow, University of California, Berkeley, 2015-2018
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 adsorbents into existing wastewater treatment infrastructure. Current research projects include selective removal of recalcitrant perfluoralkyl substances from wastewater, and design of inexpensive modified adsorbents for stormwater treatment during aquifer recharge.
