Biography

I am currently a tenure-track assistant professor jointly affiliated with Institute for Artificial Intelligence and School of Integrated Circuits in Peking University. Before joining Peking University, I was a staff research scientist and tech lead in Meta On-Device AI team with a focus on researching and productizing efficient AI algorithms and hardwares for next generation AR/VR devices. I received my Ph.D. degree in the Department of Electrical and Computer Engineering, University of Texas at Austin under the supervision of Prof. David Z. Pan and my bachelor degree in Peking University under the supervision of Prof. Ru Huang and Prof. Runsheng Wang.

My research interests focus on efficient and secure multi-modality AI acceleration algorithms and hardwares.

I am always looking for creative and self-motivated students and post docs who are interested in co-designing the future AI acceleration system. Please contact me via email with the subject line “Perspective Student from [Your Institute]” and your CV.
