Dr. Elizabeth Fassman-Beck

Principal Engineer
CrossDepartmentalTechnicalSupport

Dr. Elizabeth Fassman-Beck is a SCCWRP Principal Engineer whose primary responsibility is to implement SCWWRP’s Stormwater BMPs (best management practices) research theme. Her research in urban stormwater management quantifies the hydrologic and water quality performance of BMPs, with an emphasis on green infrastructure (GI)/Low Impact Development (LID) technologies such as living (green) roofs, bioretention systems (rain gardens and planters), permeable pavements, swales, and floating treatment wetlands. Research outcomes have led to numerous publications in highly respected journals, a co-authored technical book, Living Roofs in Integrated Urban Water Systems, and design specifications for regulatory agencies in New Zealand and North Carolina.

Prior to joining SCWWRP, her 15-year research career included academic positions at the Stevens Institute of Technology (Hoboken, NJ) and the University of Auckland (New Zealand). At Stevens, she constructed a “Living Laboratory” across the campus, including 47 field experimental GI systems, and was named the 2018 Educator of the Year from the American Society of Civil Engineers (ASCE)-NJ Section. In Auckland, she supervised or co-supervised five Ph.D.s to completion, and worked closely with the local regulatory agency to support stormwater design and policy with scientific evidence.

She received her Ph.D. and M.S. in civil engineering from the University of Virginia and her B.S. in civil and environmental engineering from Duke University. She joined SCCWRP in 2019.
