I'm currently an EECS Ph.D candidate at the University of Michigan, Ann Arbor and a member of the VLSI-SP Group advised by Professor Zhengya Zhang. I'm open to challenging opportunities before I conclude my PhD!


I received my M.S. degree in EE from the University of California, Los Angeles (UCLA) in 2015 and my B.S. degree in EE from National Tsing Hua University (NTHU). My research interest is in domain-specific computing architectures and system framework designs for accelerating machine learning, deep learning, computer vision and robotics. I have ASIC, SoC tape-out experiences in 0.18um, 40nm, 16nm and 14nm CMOS technologies. I have also built multi-camera-based PoCs for AIO products using commercial-grade FPGAs. I'm currently building an agile high-level-modeling (HLM) framework for modular and scalable domain-specific computing architecture exploration and development.

In 2018, I took a gap year from my Ph.D. to serve as a Technical Founding Partner of Iluvatar CoreX, an AI chip and systems startup based in the Silicon Valley and Greater China. In addition, I've worked as a full-time Research Scientist at Intel Labs from 2015 to 2016, held a Research Internship at Nvidia Research in 2017, a Graduate Technical Internship at Intel Labs in 2014, a Digital Design Internship at Silicon Image (Lattice) in 2014 and an SoC Design Internship at Skyviia in 2010.
