Research experience
- 4/2025 – Present: Accelerating Adaptive Algorithms At Scale through Reparameterization
- Supervisor: Prof. Rebecca Willett (The University of Chicago)
- Role: Research Assistant
- Implemented scalable approximations of EGOP: built low-rank estimation and periodic reparameterization modules based on auxiliary EGOP and randomized SVD, enabling faster convergence of Adam/Adagrad in large-scale model training without significant computational overhead.
- Conducted hyperparameter search and ablation studies on Fashion-MNIST, TinyMNIST, and EMNIST (Letters/Digits), comparing models with/without reparameterization, different optimizers, and learning-rate schedules; reported convergence speed, validation accuracy, memory footprint, and runtime to ensure reproducibility of results.

- 4/2025 – Present: Pathology Multi-Agent RAG with ARPO-Based Policy Optimization
- Supervisor: Prof. Utku Pamuksuz (The University of Chicago)
- Role: Data Scientist
- Initiated and led the overall design of a “Multi-Agent RAG + ARPO” framework in the pathology domain: applied ARPO to focus on branching exploration and step-level credit assignment at high-uncertainty tool steps, strengthening strategy learning for which agent acts, when to act, and which retrieval method to use.
- 4/2025 – Present: Deep Assortment Optimization
- Supervisor: Prof. Rui Gao (The University of Texas at Austin)
- Role: Research Intern
- Transformed discrete assortment selection into subset distribution learning, applying continuous relaxations (STGS/SIMPLE/NCPSS/SFESS) and permutation-invariant autoregressive modeling with RNN, enabling differentiable optimization under k-subset constraints.
