Research Interests

My research interest is to recover the low-dimensional structure from sparse (incomplete, corrupted) observations, and apply them to solve problems in signal processing (reservoir modeling and 3D object reconstruction)

  • Transmission tomography for high contrast structures
  • Compressive sensing and sparse structure exploitation in tight, unconventional reservoir
  • Sparse reconstruction for X-Ray discrete tomography
  • Group testing for well production measuring
  • Signal processing for plenoptic camera
