I am an Assistant Professor in the Department of Industrial and Systems Engineering at the University of Minnesota, affiliated with the CSE Data Science Initiative. My research lies at the interface of statistics, optimization, and machine learning, inspired by engineering applications.

Previously: I was an Assistant Professor in the School of Data Science at The Chinese University of Hong Kong, Shenzhen. I received my Ph.D. in Industrial Engineering from Georgia Institute of Technology, and my B.S. in Statistics from the University of Science and Technology of China in 2016.

I am actively looking for Ph.D. 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

  • Optimization and Machine Learning: diffusion generative models, large language models, transfer learning, differential privacy, adversarial robustness.
  • Statistical Inference: time series analysis, sequential hypothesis testing and change detection.
  • Applications: healthcare, including wearable sensors and electronic health record data; spatio-temporal data analysis; community detection; and manufacturing quality control.
