Dr. Gil-Ho Lee completed his B.S. in Chemistry and Physics from the Pohang University of Science and Technology (POSTECH), Republic of Korea, in 2007. He later pursued his Ph.D. in Physics at POSTECH, completing his doctoral degree in 2014. After completing his Ph.D., Dr. Lee engaged in postdoctoral research in 2014 at POSTECH, followed by a postdoctoral position at Harvard University from 2014 to 2017. In 2017, he returned to POSTECH as an Assistant Professor in the Department of Physics and was promoted to Associate Professor in 2021, a position he holds to this day. He has won several awards including Fulbright Visiting Scholar Fellowship (Fulbright Korea & the Department of State, USA, 2023), Young Scientist Award (Ministry of Science and ICT of Korea, 2022), 2023 National R&D Excellence 100 (Ministry of Science and ICT of Korea), to name a few. Dr. Lee's research primarily focuses on quantum transport phenomena, topological materials, and the integration of quantum nanodevices. His work explores macroscopic quantum effects in superconducting/graphene hybrid nanodevices, the development of single-photon detection technologies, and the study of topological superconductivity. He has made significant strides in understanding non-equilibrium quantum states, higher-order topological insulators, and relativistic electronic optics in graphene.
Dr. Lee's successfully demonstrated the formation of a steady Floquet-Andreev state in a graphene Josephson junction. This groundbreaking discovery allows for deeper investigation of non-equilibrium quantum states, an area of growing interest in condensed matter physics [Nature 2022]. Another significant contribution of Dr Lee is in the field of microwave detection technology by developing a microwave bolometer with theoretical sensitivity limits. Using the unique properties of graphene's linear band structure, he created a sensor that can detect microwave photons with unprecedented sensitivity with important implications for fields such as quantum computing, cosmic microwave background radiation research, and dark matter detection [Nature 2020]. Dr. Lee also provided the first experimental evidence showing that WTe2, a two-dimensional transition metal dichalcogenide, exhibits higher-order topological insulating properties. His work revealed the existence of a one-dimensional hinge state, a key feature of higher-order topological insulators, by spatially visualizing the current flow through a Josephson junction using an innovative interference measurement technique. This work opens up new avenues for exploring topological superconductivity and the elusive Majorana fermions [Nature Materials 2020].
