PhD Candidate

Overview

Hi, I’m Shupeng Chai. I am a PhD candidate in geotechnical engineering at Hong Kong Polytechnic University. I am currently focusing on the influences of fault roughness on rupture dynamics and stick-slip behavior through integrated laboratory experiments and numerical simulations (shown in the figure).
