Welcome to my homepage!

I am a graduate student at the Department of Mathematics , UCLA. My current research interests are optimization problems and image processing, including multidimensional signal and image processing (especially high dimensional data), hyperspectral imaging, sparse representation in signal and image. My research advisor is Stanley Osher.
