Weile Yan, Ph.D., P.E. Associate Professor

Research Interests

Water Quality Engineering; Groundwater and Subsurface Remediation; Environmental Interface Chemistry; Environmental Catalysis


  • Ph D: Environmental Engineering, (2011), Lehigh University - Bethlehem, Penn.
  • MS: Molecular Engineering of Biological and Chemical Systems, (2003), Singapore-MIT Alliance - Singapore
  • BS: Environmental Engineering, (2002), National University of Singapore - Singapore


Weile Yan received her B.Eng. and Ph.D., both in Environmental Engineering, from the National University of Singapore and Lehigh University, respectively. She was a post-doctoral associate at Princeton University before joining Texas Tech University (2011). At Texas Tech, she served as an assistant professor and later associate professor. Dr. Yan joined U Mass Lowell in 2019. Her research efforts focus on contaminant transformation mediated by earth abundant materials and reactions at natural or engineered surfaces. Her team is interested in harnessing these reactions for the restoration of contaminated environment and designing more sustainable water use/re-use technologies.
