👋 About Me

I am a Ph.D. student in the Department of Geography at the University of Wisconsin–Madison, affiliated with the
Spatial Computing and Data Mining Lab.

My research focuses on remote sensing and GeoAI, with particular interests in:

  • Hyperspectral and multispectral image modeling
  • Natural hazards (e.g., wildfire monitoring and damage assessment)
  • Precision agriculture and environmental sensing
  • Deep learning and representation learning for geospatial data

I am especially interested in learning physically meaningful and efficient representations for high-dimensional Earth observation data, bridging modern deep learning with remote sensing theory.


🔬 Current Research Topics

  • Hyperspectral image generation from extremely sparse multispectral observations
  • Transformer-based spectral–spatial modeling for remote sensing imagery
  • Wildfire burnt area and burn severity mapping using bi-temporal Sentinel-2 data
  • Hydrological streamflow prediction with graph neural networks

In the long term, I aim to develop generalizable, interpretable, and efficient spatiotemporal learning frameworks for disaster monitoring and environmental applications.
