Kimberly Gray joined the Department of Civil and Environmental Engineering at Northwestern University in 1995. After receiving her Ph.D. from the Johns Hopkins University she worked as a research engineer for the Lyonnaise des Eaux in Paris, France for 2 years. Her areas of expertise are environmental catalysis and physicochemical processes in natural and engineered environmental systems with particular focus on energy and sustainability applications. She studies the synthesis, characterization and performance of photo-active nanomaterials for application in renewable energy (CO2 reduction, water splitting), water recycling (reactive membranes for chemical oxidation and disinfection) and air quality control (cabin air, building air handling). She also studies various aspects of ecosystem goods and services, particularly as it relates to how contaminants accumulate in aquatic food webs and how nutrients are assimilated in wetlands and streams. She is particularly interested in the design and operation of sustainable cities and in solving problems of water scarcity and gender equity in developing countries such as India.
