About

  • updated: 2/1/2023

My name is Jiefeng Sun and I am a postdoc with Prof. Rebecca Kramer-Bottiglio at Yale University. My research goal is to create robotic systems that can adapt to different environments through intelligent morphological change. Toward this goal, I leverage artificial muscles and artificial-muscle-driven robots and my work spans the fields of design, physics-based modeling, and control.

I obtained my Ph.D. degree from Colorado State University in Mechanical Engineering in Aug. 2022 under the supervision of Prof. Jianguo Zhao. I earned my B.S. and M.S. in Mechanical Engineering respectively from Lanzhou University of Technology Lanzhou in 2014 and Dalian University of Technology (DLUT) in 2017. Please find my CV here. Thanks!
