About Me

I am an Assistant Professor at the Department of Electrical and Computer Engineering (ECE) at the Georgia Institute of Technology (GaTech) since 2021. Before that, I am a postdoctoral researcher in ECE, GaTech, from Sep. 2020 to Aug. 2021, and a postdoctoral researcher in ECE at the University of Illinois at Urbana-Champaign (UIUC), under the supervision of Prof. Deming Chen. I got my Ph.D. in Electrical Engineering from Waseda University in 2017, under the supervision of Prof. Takeshi Yoshimura. I got my MS and BS degrees in Computer Science and Engineering from Shanghai Jiao Tong University.

My dear husband, Dr. Pan Li, is an Assistant Professor at the CS department of Purdue University. He is working on machine learning and computation over graphs.

My Group — Sharc       

I am directing the Software/Hardware Co-design lab (Sharc) in the ECE department at Georgia Tech — twice efforts, 20 to 2000 times better!

I am looking for excellent students interested in the joint area of hardware design (FPGA, ASIC, etc.) and machine learning (DNNs, GNNs, etc.). I also have a broad interest in computer architecture, graph computation, and electronic design automation (HLS, etc.).

Research Interests

  • Software/hardware co-design: hardware-efficient machine learning algorithms and neural architecture search (NAS), ML/system co-design, on-device AI
  • High-performance reconfigurable computing: FPGA, embedded system, IoT, and edge computing
  • Graph computing: efficient algorithms and hardware for large-scale graph computation
  • Electronic design automation (EDA): high-level synthesis (HLS), domain-specific HLS
