Research Experience
Ph.D. Intern
Pacific Northwest National Laboratory (PNNL) · Richland, WA
- Research on federated learning for large-scale distributed scientific data, with a focus on heterogeneity-aware representation learning.
- Designing a Mixture-of-Experts foundation model for domain adaptation and generalization to unseen data domains, without centralizing raw data.
- Building expert routing and shared representation alignment strategies that transfer knowledge across heterogeneous sources.
- Preserving privacy, reducing communication overhead, and maintaining robust performance under domain shift.

Pacific Northwest National Laboratory (PNNL) · Richland, WA
- Conducted research on distributed learning for experimental data.
- Developed methods to align domain variations across laboratories.
- Enabled learning from heterogeneous experimental sources.
Ph.D. Intern
Pacific Northwest National Laboratory (PNNL) · Richland, WA
- Developed SCOPE, a communication-efficient framework for federated scientific datasets that leverages intrinsic data structure to handle class imbalance.
- Reduced synchronization and communication overhead while improving learning efficiency across distributed clients.
M.S. Research
Iowa State University · Ames, IA
- Developed a game-theoretic model for fair bandwidth allocation in hierarchical federated learning systems.
