Hung Nien (粘紘)
I am a Ph.D. candidate of the Electrical Engineering: Systems program in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. I work on X-ray computed tomography (CT) image reconstruction under the supervision of Prof. Jeffrey A. Fessler. My research intetests include convex optimization, iterative algorithm, compressed sensing, and computational photography. I am currently looking for a postdoctoral position in medical imaging, applied mathematics, or machine learning starting from Summer/Fall 2014.
Here are my curriculum vitae, Google scholar citation, and articles on arXiv.
My research projects have included
Convergence analysis of convex optimization method with inexact updates
Fast X-ray CT image reconstruction using variable splitting methods and ordered subsets
Blind gain correction in X-ray CT image reconstruction
Model-based light field reconstruction using a focal stack
