Lukas Graber


Lukas Graber received his M.S. and Ph.D. degrees in electrical engineering from ETH Zurich in 2002 and 2009 respectively. His Ph.D. research focused on SF6 leakage detection in gas insulated switchgear and was awarded with the ETG Innovation Prize. Before he joined Georgia Tech in 2015, he worked several years at the Center for Advanced Power System, Florida State University – initially as a post-doctoral research associate and later as a research faculty member. His focus was on superconducting power cables and fault current limiters, ultra-fast mechanical switchgear, short circuit forces in substations, and grounding aspects of power distribution on future all-electric Navy ships.


Postdoctoral Fellows:


Chanyeop Park


I received my B.S., M.S. degrees in electrical engineering from Hanyang University, Seoul, Korea (South), and my Ph.D. degree from Georgia Tech. My research focuses on investigating dielectric properties of cryogenic media for high temperature superconducting (HTS) power devices. The main goal of my research is to improve the dielectric strength of gases, as well as, to develop an improved model to accurately estimate the breakdown voltage of gas mixtures. I not only use theoretical approach but also experimental methods (plasma diagnostics) to investigate the dielectric properties of gases.
