Hi! I am an Assistant Professor at the School of CSE at Georgia Tech. Before joining Georgia Tech, I received my Ph.D. in Computer Science from UIUC in 2018, where I worked with Prof. Jiawei Han.

Research

Research Interests

The goal of my research is to develop machine learning methods that model large-scale data to solve practical and challenging problems in science and engineering. I work a lot with spatiotemporal data, text data, and graph data. In particular, I have been focused on the following topics: (1) knowledge extraction and text mining; (2) spatiotemporal data analysis; (3) uncertainty quantification for deep learning; (4) learning from limited supervision; (5) generation and optimization. More broadly, I am interested in the following topics:

  • Data Mining: Spatiotemporal Data Mining, Text Mining, Graph Mining
  • Machine Learning: Self-Supervised Learning, Weakly-Supervised Learning, Uncertainty Quantification, Decision Making Under Uncertainty
  • Natural Language Processing: Information Extraction

On the application side, I am passionate about interdisciplinary research and enjoy developing data-driven solutions to accelerate scientific discovery through close collaboration with domain experts. The techniques I develop are motivated by applications in material science, biomedical science, transportation, and public health.
