Medals of my team in a marathon race.
I am a second-year PhD student at New York University (Courant Institute). Previously I worked with Yulia Tsvekov(Prof @UW). I obtained my bachelor’s degree in EE from Xi’an Jiaotong Univerity, advised by Prof. Minnan Luo.
My research interest lies in developing training and inference methods of machine learning. I’ve been interested in how LLMs can better assist human in long horizon tasks.
