About

We study quantum nanostructures in low-dimensional materials to uncover phenomena and drive innovations in nanotechnology and quantum technologies.

Quantum Light Sources

Atomically precise quantum emitters in van der Waals materials via functionalization engineering.

Photophysics

Understanding nanoscale phenomena in carbon nanotubes and 2D materials through advanced spectroscopy.

Optoelectronics

Electrical control of excitonic properties in 2D materials via nanofabrication and quantum nanostructures.
