Dr. Rachel Scholes (she/her) is an Assistant Professor in the Department of Civil Engineering at the University of British Columbia. Her research focuses on protecting human and environmental health by addressing contaminants of concern in urban water systems. In particular, she investigates occurrence and transformations of trace contaminants with the aim of optimizing contaminant removal in engineered and nature-based treatment systems.

Dr. Scholes earned an MS and PhD in Environmental Engineering from the University of California, Berkeley, and a B.S. in Chemical Engineering from Northwestern University.
