Hello! My name is Jeongseok (pronounced "jung-sug") Lee, also known as JS.

I'm a Robotics Software Engineer in the Robotics AI team at Amazon. I build practical robot software focusing on accurate and scalable dynamics simulation for articulated mechanical systems. I'm interested in robotics, multibody dynamics simulation, motion planning, and machine learning; and passionated in software development.

I received my M.S. in the Computer Science & Engineering from the University of Washington in 2018 and a B.S. degree in the Naval Architecture and Ocean Engineering from the Seoul National University in 2006.

Previously, I worked as a Senior Software Engineer at Carnegie Mellon University with Professor Siddhartha S. Srinivasa, a Research Scientist at Georgia Institute of Technology with Professor C. Karen Liu, and a Graduate Student Researcher at Seoul National University with Professor Frank C. Park.
