People

Meet our amazing team.

We’re a talented group of research-oriented individuals interested in plasma, cryogenic power electronics, switchgear contacts, heat pipe bushing, high current impulse generators, among others.

Lukas Graber

Associate Professor

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 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.

Zhiyang Jin

Research Engineer II

Zhiyang (Yang) Jin received his Ph.D. degree from the University of Canterbury(UoC), New Zealand in 2018, and B.E., M.S. degrees from North China Electric Power University. His current research focuses on the ultra-fast mechanical switchgear and applications of superconductivity in high-voltage power apparatus. He likes outdoor activities during his free time, such as tramping/hiking and climbing mountains. His current record is Mount Tapuae-o-Uenuku (2,885m), which took him three days to finish.

Alfonso Cruz Feliciano

Research Engineer I

I received my B.S. in Electrical Engineering from Syracuse University in 2017 and my M.S. in ECE from Georgia Tech in 2019, focusing on Optics and Photonics. My research focuses on characterizing prespack IGBTs, capacitors, and coreless inductors at Cryogenic conditions. I am also researching supercritical fluid mixtures as new dielectrics to understand molecular clustering and its relationship to the electron mean free path. In my free time, I work on some DIY projects, take pictures, and read.

Graduate Students

Yang Liu

Fall 2021-Present

I received my BS and MS in Electrical Engineering from Xi’an Jiaotong University in 2009 and 2012. Afterward, I worked for the State Grid Corporation of China as a High Voltage Engineer in multiple departments and institutes, including the central office of the provincial power company in the dept. of maintenance and local research institutes. I was also enrolled in IEC as a partner member in the system committee of smart manufacturing and the system committee of smart cities. My wife and I are big fans of dogs, we have two in our home country, Tesla and Snowy, now raised by my parents.

Kayla Chuong

Fall 2022- Present

I received my B.S. in Materials Science and Engineering from Michigan State University in 2021 where I researched bioactive glass for the purpose of implant coatings. Now I am pursuing my Ph.D. degree at Georgia Tech, and my research has transitioned from biomaterials to electronics, specifically the synthesis and characterization of metal oxide varistors to be used in high voltage DC applications. In my spare time, I enjoy playing video games, reading, practicing kendo, and doing archery.

Xiang Miao

Fall 2023-Present

I received my B.S. in Electrical Engineering from Georgia Tech in 2023 and am currently pursuing an M.S. in Electrical and Computer Engineering at Georgia Tech. My research is focused on designing a modular amplifier that amplifies signals from a signal-generating board (composed of FPGA and DACs) from 3.3V to 150V through three stages of amplification. The amplifier includes six channels, making it an excellent tool for controlling each section of a piezoelectric actuator individually. In my spare time, I enjoy practicing yoga and spending time with my adorable domestic short hair cat, Chacha. I also love crocheting and knitting.
