University of Oxford

Dr. Guanchen Li

I am a Postdoctoral Research Assistant in the Department of Engineering Science, University of Oxford. I am developing continuum transport models to study the failure mechanism of solid-state Lithium-ion batteries. I am primarily interested in modelling the electrochemomechanics near metal/electrolyte interfaces to understand the dendrite nucleation process.

I received my bachelor degrees in Physics from Peking University, China, in 2011. I was awarded a Ph.D. degree in Mechanical Engineering from Virginia Tech, USA, in 2015. My doctoral research focused on the fundamental theory and modelling of far-from-equilibrium phenomena (e.g., chemical reaction, heat and mass diffusion) using a novel nonequilibrium thermodynamic framework named steepest entropy ascent quantum thermodynamics (SEAQT).

Dr. Boyang Liu

Boyang Liu received his bachelor degree (Optoelectronic Engineering) from Huazhong University of Science and Technology in China in 2014. He received his Ph. D. degree (Electronics Engineering) from the University of Maryland in the USA in 2018. During Ph.D. study under the supervision of Prof. Liangbing Hu, his research was on developing safe Li-metal batteries by applying garnet-type solid-state electrolyte with advanced interface treatment and dense-porous structural design.
