Dr. Julie Korak is an Assistant Professor in the Department of Civil, Environmental, and Architectural Engineering. Her research interests are broadly focused on water treatment engineering spanning municipal drinking water, water reuse and industrial wastewater management. Her recent projects include developing holistic water treatment and waste brine management processes for ion exchange systems and corrosion control in distribution systems. Her research has also explored using optical sensing techniques to characterize natural organic matter fate and reactivity in drinking water treatment processes. Prior to joining CU Boulder in 2018, she worked in the Water Treatment Group at the Bureau of Reclamation, U.S. Department of the Interior in Denver, CO. Dr. Korak is a licensed Professional Engineer and holds degrees in Chemical Engineering (B.S.), Environmental Engineering (B.S.), and Civil (Environmental) Engineering (M.S. and Ph.D.) from the University of Colorado Boulder. She received a National Science Foundation Graduate Research Fellowship in 2011.
