Research

My research aims to design machine learning and data-driven models to solve practical and challenging problems in science and engineering. I am particularly interested in the following topics:

  • Learning from limited supervision: weak supervision, self supervision, unsupervised learning
  • Uncertainty in ML: uncertainty quantification, active learning, decision making under uncertainty
  • Spatiotemporal modeling: spatial graphs, time series, dynamics, 3D molecular data
  • Generation and inverse design: learning for optimization, generative models, network design
  • Knowledge extraction and NLP: information extraction, multi-modal extraction, LM pre-training & fine-tuning

On the data side, I work a lot with spatiotemporal data, text data, and graph data. 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.
