About us

The Ultrafast Nano-Optics Group is led by principal investigator Professor Feng Wang. We are interested in light-matter interaction in condensed matter physics, with an emphasis on novel physical phenomena emerging in nanoscale structures and at surfaces/interfaces.

We are associated with the Physics Department at the University of California, Berkeley; the Materials Sciences Division of Lawrence Berkeley National Laboratory, and the Kavli Energy NanoSciences Institute.
