My name is Jingyan Shen. I am a first-year CS Ph.D. student at New York University (Courant Institute), advised by Prof. Matus Telgarsky and Prof. Pavel Izmailov. Previously, I earned my dual master degree from Tsinghua University and Columbia University. Prior to this, I completed my Bachelor’s degree at Wuhan University, majoring in Statistics.
I am broadly interested in machine learning and statistics, with a current focus on reinforcement learning for reasoning and planning. My current research studies when and why RL-based post-training improves reasoning in large language models. In particular, I am interested in:
- RL scaling and model priors: how the benefits and dynamics of RL post-training are shaped by what a model has already learned during pretraining or supervised fine-tuning.
- Weak-to-strong generalization: how RL can elicit stronger reasoning from limited, noisy, or weak supervision.
- Continual self-improvement: how LLMs can improve beyond fixed human-curated data through self-play, self-generated curricula, and verifier-guided exploration.
I am also fortunate to work with many great scholars and mentors, and I’m deeply grateful for their guidance.

🐰 Miscs
I value the diversity and richness of life, and I hold a deep respect for beauty and purity in all their forms. Beyond research, I enjoy playing table tennis and tennis, playing drums, losing myself in a good book, or discovering new places through travel. My recent favorite books include Flowers for Algernon and Why Fish Don’t Exist. I am also a big fan of Stephen Sondheim’s musicals, particularly Company and Sunday in the Park with George. Born in Guangzhou, I’m picky about food and I particularly enjoy Japanese and Cantonese cuisine for their focus on fresh ingredients and natural flavors.
