I am Qiumin Xu, Ph.D.

I'm currently a software engineer at Google, working on the performance of machine learning accelerators. I recently completed my Ph.D. degree in the Super Computing in Pocket Group at the University of Southern California (USC). My advisor is Professor Murali Annavaram.

Before coming to USC, I received my B.S. degree from Department of Microelectronics in Electrical Engineering and Computer Science School, Peking University in 2011.

During my Ph.D., I worked on improving energy efficiency and security of GPUs. I also worked on storage systems, mobile computing and internet of things during internships at Samsung, NVIDIA and HUAWEI.

Here are my DBLP, Google Scholar profile and more information about my education, industry and teaching experience.
