Sinong (Simon) Zhan
I am a 3rd year PhD student in the ECE department at Northwestern University, advised by Qi Zhu. Before Northwestern, I did my undergrad in Applied Math and Computer Science at UC Berkeley, where I was advised by Sanjit A. Seshia. I am currently a Research Intern at Google Research, working with Maryam Karimzadehgan and Benny Schlesinger. Previously, I spent a great time as a research intern at Amazon SFAI.

Research
My research lies at the intersection of reinforcement learning, formal methods, and AI safety. I design safe and delay-robust RL algorithms that integrate formal verification — barrier certificates, constraint satisfaction — with learning-based control to provide provable guarantees for autonomous systems. More recently, I have been developing specification-guided frameworks that leverage formal specifications (temporal logics, program contracts) to systematically evaluate, steer, and explain foundation-model-based agents, addressing the challenge of bridging informal human safety intent and provably correct agent behavior. This agenda has led to publications in venues such as ICML, NeurIPS, ICLR, CVPR, CCS, ICCPS, L4DC, FM, RV, and IROS.
