Lawrence Yunliang Chen

I am a 3rd year PhD student at UC Berkeley IEOR, advised by Professor Ken Goldberg. My research interest lies in the intersection of Robotics and Machine Learning. I am a member of the AUTOLAB, which is part of the Berkeley Artificial Intelligence Research (BAIR) Lab. I am supported by the NSF Graduate Research Fellowship. I did my undergraduate at UCLA with double majors in Applied Math and Statistics, where I was advised by Professor Jungseock Joo.
