Hi! :wave: I’m a research scientist with Llama Research team, Meta Superintelligence Labs. I build next-generation Llama models by advancing their reasoning and coding capabilities.

I obtained my Ph.D. degree from Department of Computer Science and Engineering at The Ohio State University in 2024, advised by Prof. Zhiqiang Lin. My research interests broadly lie in large language models (LLMs), coding generation, program/binary analysis, and security.

I am always looking for opportunities to collaborate. The best way to reach me is via email: jin (dot) 967 (at) osu (dot) edu.
