CPES congratulates our 3 most recent graduates!
May 29, 2019
Christina DiMarino joined the Center for Power Electronics Systems (CPES) at Virginia Tech in 2012 as a direct Ph.D. student. In 2014, Christina earned her Master's degree at CPES for her work on the high-temperature characterization of silicon carbide (SiC) transistors. In 2015, Christina participated in an international research exchange program at the University of Nottingham. During this exchange, she worked with Professor Mark Johnson and a team of researchers on the design of a high-density package for 10 kV SiC power MOSFETs, which is the focus of her Ph.D. Since 2015, Christina has been the Student Membership Chair for the IEEE Power Electronics Society (PELS). Christina is on the committees for the PELS Students and Young Professionals, IEEE International Technology Roadmap for Wide-Bandgap Power Semiconductors, and PELS Mentorship Program. During her graduate studies, Christina has had internships with General Electric, Wolfspeed (a Cree company), and Sumitomo Electric Industries. In January 2018, Christina joined Virginia Tech as an assistant professor.
Sungjae Ohn completed his Ph.D. program in February 2019. His dissertation, "Circuits and Modulation Schemes to Achieve High Power Density in SiC Grid-connected Converters" and defense presentation are available online CPES Principal Plus, Principal, and Associate members via password access. Sungjae received his B.S. degree and M.S. degree from Seoul National University, Seoul, Korea in 2013 and 2015. He joined Center for Power Electronics Systems, Virginia Polytechnic Institute and State University in Aug 2015 and completed his Ph.D degree in 2019. Sungjae's research is focused on magnetic integration, EMI mitigation and containment strategy for SiC converters, and soft-switching techniques for SiC-based three-phase converter. He currently works as a Research Associate at CPES.
During his time at CPES, he chaired the Publication committee for the 2017 CPES Annual Conference and served as a member of the CPES student council in 2018-2019. In his spare time, he loves listening to music, playing piano, and swimming.
Qiong Wang received his B.S. degree in electrical engineering from Tsinghua University, Beijing, China in 2012. He then joined Center for Power Electronics (CPES) at Virginia Tech. He received his M.S. and Ph.D. degree from Virginia Tech, Blacksburg, USA in 2015 and 2018, respectively. He stayed at CPES as a research scientist upon graduation, and then joined Google as a power engineer.
Outside of work, he enjoys playing basketball, tennis, video games, board games (well, all kinds of sports and games) with friends. And he started to pursue things that allows him to explore the world outside of power electronics: hiking, scuba diving and skiing.
