Hi! I am Letian (Zac) Chen, a second-year PhD student at Georgia Tech. I received my Bachelor’s degrees in psychology and computer science from Peking University in 2018 and a Master’s degree in computer science from Georgia Tech in 2020. Prior to joining the CORE Robotics lab, I was in CVDA (CS) and CDLab (Psy) at Peking University (Beijing, China). I love researching and implementing cool stuff that works on robots. I am interested in all kinds of intelligence problems, both artificial intelligence, and human intelligence. Specifically, I look into the intelligence problem through reinforcement learning perspective. My research enables robots to infer human’s intent in Learning from Demonstration settings, teasing out heterogeneity and suboptimality from the demonstrations. I envision a future where everyone has the ability to teach robots effortlessly and robots become a valuable part of our life through my work.
