The Utzat Group
Nano-Optics & - Spectroscopy

We study nanoscale light-matter interaction

Welcome! We’re building an interdisciplinary team of chemists, physicists, and materials scientists driven to understand and ultimately control the light-matter interaction at the nanoscale. We seek to exploit expertise in single-molecule spectroscopy, electron microscopy, inorganic materials synthesis, and nanofabrication to gain exquisite control over photonic, electronic, spin, and vibrational degrees of freedom and their couplings.

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’re enthusiastic about sharing our approach to culture and science outside of academia.
