About me

I am a third-year Ph.D. student at MIT JTL Transit Lab supervised by Prof. Jinhua Zhao. I previously received my M.Eng degree at McGill University, supervised by Prof. Lijun Sun. Before that, I obtained my Bachelor’s degree in Mechanical Engineering from Shanghai Jiao Tong University and was a research assistant at National University of Singapore. My supervisors at two universities are Prof. Jiangang Jin and Prof. Lee Der-Horng respectively. Click here to view my up-to-date CV. If you want to know more about me, please feel free to contact me (dingyi@mit.edu) and schedule a 30-min short talk.

Research Interests

  • Urban computing & smart city
  • Graph neural network
  • Time Series
  • Spatiotemporal data mining
  • Network science
  • Bayesian probabilistic factorization models

Four particular questions I try to study and connect together:

  1. Spatiotemporal data mining: imputation, forecasting, kriging, and dynamic kriging. Particularly applying Graph Neural Networks.
  2. Uncertainty quantification: forecasting with prediction intervals (Baysian or Frequentist ways) and ensuring reliable prediction intervals
  3. Unstructured data integration and interpretation: images, virtual & physical networks, textual data
  4. Equity and social consideration: mitigating biases (e.g. fariness) in deep learning and AI for humand development
