Ph.D. Stanford University.
My research interests include medical imaging, tomography, nonparametric estimation, and inverse problems, with current and past projects in X-ray CT, MRI, PET, SPECT, radiation therapy, and image registration. I am interested both in developing algorithms for these problems, as well as analyzing and predicting the properties of these algorithms.
