Research Interests


My broad research interests are in the fields of computational imaging, image processing, signal processing, and computer vision. In particular, I am interested in inverse problems in a variety of biomedical imaging techniques such as positron emission tomography (PET), single-photon emission computed tomography (SPECT), Compton imaging, X-ray CT, and magnetic resonance imaging (MRI). The current research projects focus on developing super-resolution image reconstruction methods for PET via sparse coding and example-based learning.
