About Me

Jianchang Su

"道阻且长,行则将至"

— 《荀子·修身》

I am a Ph.D. candidate at University of Connecticut in the School of Computing. My research focuses on building efficient, scalable, and trustworthy infrastructure for cloud computing and ML/LLM systems. I work on systems-level optimization for distributed training and serving, with the goal of addressing performance bottlenecks and security challenges in modern computing environments. I received my Master's degree in Artificial Intelligence from Friedrich-Alexander-Universität Erlangen-Nürnberg and my Bachelor's degree in Electrical Information Engineering from Shanghai Normal University.
