Molecular Nanophotonics

Molecular Nanophotonics

We're an experimental research effort in UC Berkeley's College of Chemistry and at Lawrence Berkeley National Lab. We use concepts from quantum optics and nanophotonics in the chemical sciences with two objectives: advancing methods in single-molecule spectroscopy, microscopy, and sensing; and designing material systems with coherent modes of action useful in quantum information science and energy transduction.

We care about culture

We work together to create an inclusive and equitable culture conducive to creative accomplishment and individual growth. The Utzat group welcomes all (becoming) scientists regardless of their gender, cultural or socioeconomic background, sexual orientation, race, age, or cognitive style. We believe our approach to culture helps drive our scientific accomplishments.
