About me

Hi, my name is Jiajun Huang (黄嘉俊). I will be joining the University of South Florida (USF) as an Assistant Professor in Fall 2025 and am hiring multiple Ph.D. students. I am currently a CS Ph.D. candidate at the University of California, Riverside supervised by Dr. Zizhong Chen, and I will be graduating in June 2025. I have also been a long-term research intern at the MPICH team and SZ team in the Argonne National Laboratory, where I have collaborated with Dr. Sheng Di, Dr. Yanfei Guo, Dr. Rajeev Thakur, and Dr. Franck Cappello.

I am the founder of ZCCL.org, an initiative developed in collaboration with scientists at Argonne National Laboratory. ZCCL.org is dedicated to advancing both compression and communication and has introduced the first compression-accelerated collective communications library–ZCCL, enabling direct communication and computation with compressed data. You can explore my publications here. Feel free to reach out to me at jhuan380(at)ucr.edu.

Job Opportunities

I am actively recruiting 3–4 highly motivated Ph.D. students with full scholarships to join my research group. Areas of focus include high-performance computing and communication, high-performance deep learning, parallel & distributed computing, and big data management & analytics.
