Kofi Christie earned his PhD in environmental engineering at Vanderbilt University in May 2020, where he worked to advance water treatment and desalination technologies for high-salinity wastewater. His thesis focused on expanding our understanding of membrane distillation through module-scale thermodynamic analysis and elucidation of the causes and effects of inorganic fouling on membrane surfaces. After receiving his PhD, Kofi joined the Andlinger Center for Energy + the Environment at Princeton University as a recipient of the Presidential Postdoctoral Fellowship. At Princeton, he explores the intersection of membrane separation and crystal nucleation to sustainably recover solid and liquid resources from wastewater streams associated with hydrocarbon combustion.
