Interfacial Engineering for Water and Resource Sustainability
Interfacial phenomena play a paramount role in a wide range of natural and engineered environmental processes. Our first goal is to understand the physics and chemistry of interfaces and colloids relevant to environmental processes. We utilize nanoscale experimental techniques including quartz-crystal microbalance with dissipation monitoring, atomic force microscope, and electrochemical impedance spectroscopy to probe interfacial processes. Our second goal is to leverage the insights from fundamental interfacial science studies to innovate materials and devices for tackling the grand challenges of water and resource scarcity. Our current research interests include mitigation of surface fouling and scaling, electrochemical technologies for selective ion separation, and groundwater remediation using colloidal amendments.
