Jeric Lew

Hello, I'm Jeric! I am currently pursing a Masters of Engineering by research and I'm incredibly lucky to be advised by Professor Guillaume Sartoretti @ MARMot Lab, National University of Singapore (NUS). I recently completed my Bachelor of Engineering in Mechanical Engineering @ NUS, and was also advised by Professor Sartoretti for my undergraduate thesis on diffusion models for autonomous robot exploration.

I am actively seeking PhD opportunities around the world that are relevant to Robot Learning!

Research

My research interest is in the intersection of robotics, computer vision and machine learning to develop robots that can reason about their surroundings and other agents (robots or humans) to complete difficult tasks like autonomous exploration, off-road navigation, and manipulation alone or in teams. I believe that this line of research (robot learning) will lead to capable and adaptable robots that can propel robotics applications in the real world. Currently, I am working on learning strategies for multi-robot systems to improve coordination and task efficiency.

In Summer 2024, I was working on off-road navigation as a Research Intern @ Carnegie Mellon University's (CMU) Robotics Institute as a part of CMU's Robotics Institute Summer Scholars (RISS) program, under the supervision of Professor Sebastian Scherer and Dr. Wenshan Wang.
