MS/Ph.D., Environmental Engineering In Progress, Colorado School of Mines, Colorado

B.A., Chemistry and Physics (2017), Coe College


Andrew joined the Strathmann Research Group in the Fall of 2018 following a Fulbright Fellowship in Sri Lanka. As an undergraduate, he conducted computational materials science research on borate glasses and crystals at Coe College, and studied advanced oxidation processes for water treatment under Dr. David Cwiertny at the University of Iowa. Currently, Andrew is a member of the Reinventing the Nation’s Urban Water Infrastructure (ReNUWIt) Engineering Research Center, where he conducts research on energy and nutrient recovery from wastewater. This research includes biochemical-hydrothermal-catalytic conversion processes for producing fuels and chemicals from wastewater-derived organic carbon, and phosphorus recovery as struvite from domestic wastewater. His work also includes characterizing and testing heterogenous catalysts for biomass conversion.  Andrew is co-advised by Dr. Derek Vardon and is a member of the Vardon Research Group at the National Renewable Energy Laboratory (NREL).
