Prof. Donghun Lee is an experimentalist in the field of quantum optics and condensed matter physics. His research focuses on hybrid quantum systems and quantum sensing and imaging applications based on solid-state spin qubits i.e. nitrogen-vacancy defect centers in diamond. He received B.S. degree from POSTECH and earned Ph.D. degree at Ohio State University with the study of scanning tunneling microscopy on single dopants in semiconductors. He did his postdoctoral research at Yale University in the field of cavity optomechanics. Before joining Korea Universiy, he was an associate specialist at University of California at Santa Barbara (UCSB) conducting diamond NV centers related research.
