PhD candidate, Rutgers Computer Science. On the job market—feel free to reach out.

About me

I am a Ph.D. candidate in Computer Science at Rutgers University, advised by Prof. Dong Deng. My research centers on near-duplicate text alignment and deduplication for large-scale LLM pretraining datasets, vector databases and approximate nearest neighbor (ANN) search, and sparse attention for efficient LLM inference. Previously, I was a research intern at Alibaba Cloud. I am open to discussions and collaborations, and I am currently on the job market for 2026. Feel free to reach out at zhencan.peng@rutgers.edu.
