Qiang Xu

Ph.D. Candidate
School of Electrical and Computer Engineering
Purdue University

I am a last-year Ph.D. student in School of Electrical and Computer Engineering at Purdue University, supervised by Prof. Y. Charlie Hu. I am interested in mobile systems, edge computing, and their intersection with machine learning. My recent research focuses on building efficient machine learning inference systems for emerging applications like augmented reality. I received my B.E. in Computer Science and Technology from University of Science and Technology of China (USTC) in 2018.

I will be joining Nvidia as a Developer Technology Engineer in the summer of 2024.
