Thermal-Fluid Science for Sustainable Energy

Boiling water at 30 W/cm² on a smooth SiO₂ surface

Welcome!

I am a postdoctoral associate in the Thermal Energy Group at Lawrence Berkeley National Laboratory.

I am broadly interested in multiphase thermal-fluids and materials innovations for energy applications. My research is currently focusing on PCM-based thermal energy storage technologies and thermal switches.

Please feel free to contact me with any inquiries about my research and publications.
