Lei Zhao

I got my Ph.D. from University of Pittsburgh in 2022. I received my B.S. degree of Software Engineering in 2011 and M.S. degree of Computer Science in 2014 respectively from Northwestern Polytechnical University in China. After graduation, I worked as a postdoctoral research scientist in Meta Reality Labs from 2022 to 2023 and Hewlett Packard Labs from 2023 to 2026. Now I am an AL and Machine Learning Engineer in HP Labs.

Research

I specialize in the design and optimization of neural network accelerators, spanning architecture, compiler, and system levels. My expertise includes MLIR-based compiler development, accelerator simulation and performance analysis, and hardware–software co-design for efficient deep learning execution. While I have extensive experience in in-memory computing and emerging memory technologies, my broader focus is on advancing AI hardware architectures and compiler frameworks for next-generation machine learning systems.

Although my recent projects involve in-memory and analog computing, my primary expertise is in computer architecture and system design. I leverage existing compute units to build complete accelerators, compiler toolchains, and model optimization frameworks—an approach that readily generalizes to any hardware architecture or technology.
