Junxiang (Jim) Wang | 王俊翔

Ph.D. student, Carnegie Mellon University



I am a first-year Ph.D. student at Carnegie Mellon University, advised by Prof. Zackory Erickson. I obtained my B.S. in Mechanical Engineering and M.S.E. in Robotics from Johns Hopkins University, where I was fortunate to work with Prof. Peter Kazanzides, Prof. Iulian Iordachita, and Prof. Chien-Ming Huang.

I am interested in designing robots that exhibit safe and intelligent behaviors that are human-like and/or natural to humans interacting with the robot.

In my free time, I enjoy long-distance running (racing up to half-marathons), tennis, skiing, and photography.
