Chang Liu, 刘畅, is a staff research physicist at the Theory Department of the Princeton Plasma Physics Laboratory. His current research lies in the field of energetic particle (EP) and runaway electron (RE) physics in tokamaks and stellarators, where he engages in theoretical analysis and numerical simulations.

Chang is the primary developer of the EP and RE simulation modules within the M3D-C1 extended magnetohydrodynamics (MHD) codes. He explores various types of MHD and whistler modes driven by EPs and REs, investigating their impact on particle confinement. Additionally, he dedicates his efforts to algorithm development and optimizing codes for GPUs. His research interests extend to areas such as high-energy density plasma (HEDP), plasma wave theory, and fundamental gyrokinetic theory.

He received his PhD in 2017 from Princeton University, studying the physics of runaway electrons in tokamaks, advised by Dr. Dylan Brennan and Prof. Amitava Bhattacharjee. He received his Bachelor's degree in 2011 from Peking University in China.
