Research Interests
Interfacial and Separation Technology
for Water and Resource Sustainability
Interfacial phenomena play a paramount role in a wide range of natural and engineered environmental systems. Our first goal is to understand the physics and chemistry of interfaces and colloids relevant to engineered 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, processes, and devices for tackling the grand challenges of water and resource scarcity.
Our research aims to develop more durable, cost-effective, selective, and electrified separation processes. The tools we use include colloid and interface science, electrochemistry, and techno-economic assessment. We currently explore the application of interfacial and separation technologies in 1) water desalination; 2) groundwater remediation; and 3) recovery of critical materials from water streams.
