Kehan Long

I work on robotics at SceniX.ai.

I did my Ph.D. in Mathematics at University of California San Diego, where I worked on robotics at Contextual Robotics Institute and was fortunate to be advised by Prof. Nikolay Atanasov, Prof. Jorge Cortés, and Prof. Melvin Leok.

My academic journey began at the University of Illinois,Urbana-Champaign, where I obtained a B.S. degree in Applied Mathematics.

Research Interests

My research lies at the intersection of robotics, artificial intelligence, and control theory, with a focus on enabling certifiable and reliable robot autonomy. I develop methods for robot control and learning, decision-making under uncertainty, and safe robot autonomy, combining theoretical guarantees with practical applicability for real-world robotic systems.
