Our Group

Our research takes advantage of emergent quantum materials and state-of-the-art quantum sensing techniques with an ultimate goal to develop hybrid quantum systems for next-generation information technologies. Our research tools are versatile, including magnetron-sputtering, optical measurement based on spin defects in semiconductors (nitrogen vacancy centers in diamond, boron vacancy centers in hBN, etc), transport and microwave spectroscopy as well as scanning probe magnetometry.

Openings

We are recruiting at all levels. We are looking for motivated postdocs. If you are interested, please email (hwang3021[at]gatech.edu) to discuss research opportunities.
