Jinjun Liu received the B.S. and Ph.D. degrees in electrical engineering from Xi’an Jiaotong University (XJTU), Xi’an, China, in 1992 and 1997, respectively.

He then joined the XJTU Electrical Engineering School as a faculty. From late 1999 to early 2002, he was with the Center for Power Electronics Systems, Virginia Polytechnic Institute and State University, Blacksburg, VA, USA, as a Visiting Scholar. In late 2002, he was promoted to a Full Professor and then the Head of the Power Electronics and Renewable Energy Center at XJTU, which now comprises more than 20 faculty members and over 200 graduate students and carries one of the leading power electronics programs in China. From 2005 to early 2010, he served as an Associate Dean of Electrical Engineering School at XJTU, and from 2009 to early 2015, the Dean for Undergraduate Education of XJTU. He is currently a XJTU Distinguished Professor of Power Electronics. He coauthored 3 books (including one textbook), published over 500 technical papers in peer-reviewed journals and conference proceedings, holds 70 invention patents (China/US/EU), and delivered many plenary keynote speeches and tutorials at IEEE conferences or China national conferences. His research interests include modeling, control, and design methods for power converters and electronified power systems, power quality control and utility applications of power electronics, and micro-grids for sustainable energy and distributed generation.

Dr. Liu received for many times governmental awards at national or provincial/ministerial level for scientific research/teaching achievements. He also received the 2006 Delta Scholar Award, the 2014 Chang Jiang Scholar Award, the 2014 Outstanding Sci-Tech Worker of the Nation Award, the 2016 State Council Special Subsidy Award, the IEEE Transactions on Power Electronics 2016 and 2021 Prize Paper Awards, and the Nomination Award for the Grand Prize of 2020 Bao Steel Outstanding Teacher Award. He served as the IEEE Power Electronics Society Region 10 Liaison and then China Liaison for 10 years, an Associate Editor for the IEEE Transactions on Power Electronics since 2006, and 2015-2019 Executive Vice President and 2020-2021 Vice President of IEEE PELS, and was elevated an IEEE Fellow in 2018. He was on the Board of China Electrotechnical Society 2012-2020 and was elected the Vice President in 2013 and the Secretary General in 2018 of the CES Power Electronics Society. He was the Vice President for International Affairs, China Power Supply Society (CPSS) from 2013 to 2021, and since 2016, the inaugural Editor-in-Chief of CPSS Transactions on Power Electronics and Applications. He was elected the President of CPSS in Nov.  2021.  Since 2013, he has been serving as the Vice Chair of the Chinese National Steering Committee for College Electric Power Engineering Programs.
