Juo-Tung (Justin) Chen

I am a PhD Student @ Johns Hopkins University in Mechanical Engineering, advised by Axel Krieger in the Intelligent Medical Robotic Systems and Equipment Lab (IMERSE).

I received my Master's degree in Robotics from Johns Hopkins University and my Bachelor's degree in Biomechatronics Engineering from National Taiwan University. During my masters, I worked in Intuitive Computing Lab advised by Chien-Ming Huang , and during my undergrad, I worked in Robots and Medical Mechatronics Lab (RMML) advised by Ping-Lang Yen.
