Optofluidics and Energy

We work on optofluidics and microfluidics for energy.  The efforts range from solar water splitting devices to solar thermal energy conversion. Specifically, we make use of microfluidic platforms to enhance the efficiency of energy conversion processes, and achieve device functionalities unattainable by classical electrochemical reactor designs. Current projects include the development of membraneless water-splitting devices, air-based electrolyzers, and photoelectrochemical hydrogen generators.
