About me

I obtained my Ph.D. from the Electrical Engineering: Systems program in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. I worked on X-ray computed tomography (CT) image reconstruction under the supervision of Prof. Jeffrey A. Fessler, and I am now working as a postdoctoral research fellow in the same group.

My research interests include convex optimization, iterative algorithm, compressed sensing, and computational photography. I am seeking a professional position in imaging and machine learning research to dedicate myself with my knowledge and skill set in mathematical optimization.

Here are my resume, Google scholar citation, and articles on arXiv.

Research

My research projects have included

  • Model-based tomographic reconstruction of translucent objects using lenslet-based plenoptic cameras

  • 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
