Dr. C. Li
The goal of our research is to explore and build the next-generation hardware based on post-CMOS emerging devices, e.g. memristors. From top-down, we examine the existing algorithms and determine the most crucial task to accelerate with our hardware. Examples include but not limited to matrix multiplication in A.I./machine learning tasks. In the meanwhile, we optimize and characterize the device performance, including their nonlinear dynamics, and build novel circuit/architecture/algorithm from the bottom up.
Dr. Can Li is currently an Assistant Professor at Department of Electrical and Electronic Engineering (EEE) of the University of Hong Kong (HKU), working on analog and neuromorphic computing accelerators based on post-CMOS emerging devices (e.g. memristors), for efficient machine/deep learning, network security, signal processing, etc. Before that, He spent two years at Hewlett Packard Labs in Palo Alto, California, and obtained his Ph.D. from University of Massachusetts, Amherst, and B.S./M.S. from Peking University.
