Xin Dong

Cambridge, MA, May 2020

I am a research scientist at NVIDIA Research. I received Ph.D. in Computer Science from Harvard University in 2023, advised by H.T. Kung. I have general research interests in deep learning, with a focus on designing accurate, efficient and trustworthy systems for autonomous machines, LLM and GenAI.

Prior to Harvard, I was a research assistant at Nanyang Technological University and UC San Diego. I am a recipient of the Harvard James Miller Peirce Fellowship.
