Jiachen Sun

Ph.D. Candidate

Computer Science and Engineering,

University of Michigan, Ann Arbor



I will join TikTok (San Jose) as a machine learning scientist working on responsible recommendation this Dec.
I'm a 2nd-year 3rd-year 4th-year 5th-year Ph.D. candidate [CV] in Computer Science and Engineering at the University of Michigan supervised by Professor Z. Morley Mao. I got my bachelor degree from Zhiyuan College at Shanghai Jiao Tong University advised by Professor Xiaohua Tian. I had a happy time working at DiDi AI Lab as an algorithm engineer intern during my senior year under the supervision of Professor Jieping Ye. I was also fortunate to work with Professor Haitham Hassanieh as a research intern at the University of Illinois Urbana-Champaign in the summer of 2017. I spent my summer semester of 2016 as an exchange student at the University of Washington.

My research interests are broadly in deep learning, computer vision, cyber-physical security, and machine learning systems, with a current focus on adversarial machine learning and trustworthy AI.

I joined Uber Marketplace Pricing team an Ph.D. research MLE intern in the summer of 2023 working on product-level deep learning model robustness. I joined Meta/Facebook AI as a research intern in the summer of 2022 mentored by Dr. Caner Hazirbas and Dr. Ivan Evtimov, focusing AI integrity and out-of-distribution robustness. I interned at Lawrence Livermore National Laboratory (LLNL) in the summer of 2021 supervised by Dr. Bhavya Kailkhura and Dr. Pin-Yu Chen on the topic of certified adversarial robustness in deep learning. I also closely work with Professor Chaowei Xiao from ASU and NVIDIA Research who has been supporting my research since 2020.

I love sports, and was a national second-class athlete. My records: 11.5 seconds for 100 meters race, and 1.7 meters for high jump. Besides Track and Field, I also love playing soccer, basketball, and volleyball. Mamba Forever! RIP Kobe Bean Bryant. I also love e-sports like League of Legends, PUBG, and CS:GO. I am a beginner of snowboarding and reallllly enjoy it this snow season!
