Research Summary

Research   My research is in statistical and sequential signal processing and applications in medical imaging and computer vision. Currently, my focus is on:

• Recursive robust PCA
• Recursive sparse recovery (compressive sensing)
• Medical Imaging (MRI reconstruction)
• Older and still ongoing work
• Sequential Monte Carlo (particle filtering) for large dimensional sequential state estimation
• Change detection in noise-corrupted nonlinear systems
• Computer Vision (deformable contour tracking and landmark shape tracking)

Professional Service:

• Associate Editor, IEEE Transactions on Signal Processing, 2009-present
• Organized a special session recursive reconstruction of sparse signal sequences at Asilomar 2010
• Tutorials chair for IEEE Intl. Conf. Image Proc. (ICIP) 2008
• Area chair (TPC member) for ICIP 2009 for interpolation
• Program committee member of  CVPR,2008, 2009, ECCV and  ICCV, 2007
• Reviewer for IEEE Trans. Signal Proc., IEEE Trans. Image Proc., IEEE Trans. PAMI and others and for various conferences (ICASSP, ICIP, CDC,...)
