We create and apply new tools to understand complex Environmental Interfacial Chemistry (EIC) processes. The EIC Lab is an interdisciplinary research team devoted to developing and applying novel technologies for a fundamental understanding of the complex Environmental Interfacial Chemistry processes. Specifically, we develop a host of methods that enable visualization of Environmental Interfacial Chemistry processes at the single-particle, -cell, and -molecule level. We are applying these technologies for studying microbial attachment and charge transfer, and catalytic conversion of pollutants.


Developing novel optical techniques to image chemical reactions in aquatic solution.


Probing the catalytic degradation of pollutants at the single-particle or single-molecule level.


Exploring the microbial cell interacting with surface, including cell-cell interactions, biofilm formation, biodegradation, pathogen detection, and extracellular electron transfer.


Designing novel technologies for precise capture and conversion of pollutants.
