Accepting Graduate Students

I am actively looking for PhD students to join my research group in Fall 2025 or 2026. Please send me an email with your CV and transcript if you are interested.

Research Interest

My research interest lies in the interface of statistics, optimization, and machine learning, inspired by important applications.

• Statistical Inference: Time series analysis, sequential hypothesis testing and change detection.

• Optimization and Machine Learning: Diffusion models, synthetic data generation, data-driven decision-making under uncertainty, distributionally robust methods, and adversarial robustness.

• Applications: Healthcare (wearable sensors and electronic health record data), spatio-temporal data analysis, community detection, and manufacturing quality control.
