About me



Hi, my name is Yinpei Dai (戴音培), and I am a first year Ph.D. student at Situated Language and Embodied Dialogue (SLED) Lab, University of Michigan, Ann Arbor. Previously, I was a senior algorithm engineer at Alibaba DAMO Academy. I received my M.S. degree in the Department of Electronic Engineering, Tsinghua University. at Speech Processing and Machine Intelligence (SPMI) lab, advised by Professor Zhijian Ou. I received my B.S. degree in Mathematics and Physics from Tsinghua University in 2016.

My main interest is embodied AI. I am especially interested in vision & language navigation, human-robot interaction and multi-modal dialog systems.
