I am a senior research technologist in Memory Technology, Western Digital R&D Engineering since 2021. I was a research scientist in Computing Technology Lab in Alibaba Research from 2019 to 2021. I was a principal researcher in HGST Research from 2014 to 2019. I received my Ph.D. in Electrical Engineering in Sept. 2014 from the Department of Electrical and Computer Engineering, UCSD, where I was also associated with the Center for Memory and Recording Research (CMRR) from 2010 to 2014. My Ph.D. advisor was Prof. Siegel. I entered Department of Electronic Engineering, Tsinghua University, Beijing, China in Sept. 2005 and graduated in June 2009.

My research focus is on algorithm and architecture co-design. In AI, I developed deep learning acceleration to jointly optimize deep learning algorithms and hardware architectures. Specifically for LLM, I designed memory architecture that enables faster and noise tolerant inference. I am also interested in the robustness of deep neural networks against errors from media and computing, training neural networks with the presence of noise, etc. In Information Theory, I am interested in coding, signal processing, and system architectural design for non-volatile memories, encoding and decoding of BCH, LDPC and polar codes, and coding for distributed storage. My personal interests also includes math puzzles and games.
