Dong comes to Virginia Tech from the Electric Power (EP) research organization at GE Global Research Center in Niskayuna, NY, where he developed mid to long-term power conversion and electric power system technology for several GE businesses. During his tenure at GE, Dong was involved with multiple research and development programs and technology initiatives, like medium-voltage dc (MVDC) for offshore vessels, hybrid energy storage modules (HESM) for Navy, and SiC power electronics building block (PEBB) for renewable energy integration. He has received several awards, including the Gold Medallion Patent Award, Publication Award, and Technology Transition Award.

From 2007-2012, Dong was a research assistant at Virginia Tech's Center for Power Electronics Systems (CPES).

His research interests include modeling, design, and digital control of power electronic systems; low-voltage to medium-voltage SiC high-frequency power electronics; high-power resonant converters and high-frequency transformer; power conversion systems for grid, renewable energy integration, and transportation electrification; and real-time hardware-in-loop (HIL) simulation.

Dong has been published in more than 15 journals and has written more than 45 IEEE conference papers. He received a 2nd Prize Paper award from IEEE Transactions on Power Electronics in 2017. He currently holds 16 U.S. patents and has more than 16 U.S. patent applications. He serves as the associate editor of IEEE Transactions on Industry Applications, vice chair of IEEE Industry Applications Society (IAS) Schenectady Region Chapter, and is an organizing committee member of the IEEE Energy Conversion Congress and Expo (ECCE) conference.

Dong received his B.S. degree (2007) from Tsinghua University, Beijing, and his M.S. (2009) and Ph.D (2012) in electrical engineering from Virginia Tech.
