Dingyi Zhuang

Ph.D. in Transportation @ MIT


About me

I am a fourth-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

Bring AI techniques to transportation engineering and urban planning.

Urban:

  • Urban computing
  • Spatiotemporal data mining and pattern discovery
  • Travel behavior analysis

AI:

  • Graph neural network
  • Generative AI
  • Reinforcement learning
  • Trustworthy AI

Four particular questions I studied and try to connect together during my Ph.D.:

  1. Spatiotemporal data modeling: 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
