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
