Bio
I am currently a 3th-year Ph.D. student in the Department of Computer Science & Engineering, Texas A&M University. My advisor is Prof. Shuiwang Ji, who leads the Data Integration, Visualization, and Exploration (DIVE) Laboratory . I obtained my Master’s and Bachelor’s degrees from Shanghai Jiao Tong University in 2023 and 2020, respectively. Here is my CV.
My research focuses on generative modeling and optimization, with an emphasis on discrete diffusion models, reinforcement learning methods, and large language models. I am the author of Seq2Exp, a framework that leverages large language models to capture causal relationships between DNA and epigenomic data for gene-expression prediction, which was selected as an oral paper at ICLR 2025. I also proposed VIDD (Iterative Distillation for Reward-Guided Fine-Tuning of Diffusion Models in Biomolecular Design), which develops reinforcement learning to fine-tune discrete diffusion models.
