Bio

I am currently a research scientist at Meta Reality Labs Research (f.k.a. Facebook Reality Labs Research, Oculus Research). I received the B.E. degree in electronic information engineering from University of Science and Technology of China, Hefei, Anhui, China, in 2015, and the M.S. degree in 2019 and the Ph.D. degree in 2021 from The Ohio State University, Columbus, OH, both in computer science and engineering. During my Ph.D. study at Ohio State, my research focused on speech enhancement and separation. I was advised by Prof. DeLiang Wang, who leads the Perception and Neurodynamics Laboratory.

My research interests include speech enhancement, speech separation, speech dereverberation, microphone array processing, audio-visual speech processing, acoustic echo cancellation, and deep learning. I serve as a reviewer for IEEE/ACM Transactions on Audio, Speech, and Language Processing, IEEE Journal of Selected Topics in Signal Processing, IEEE Signal Processing Letters, IEEE Communications Letters, The Journal of the Acoustical Society of America, Speech Communication, Neural Networks, Pattern Recognition, and Neurocomputing.
