I’m Ju Sun, a Math+X postdoctoral scholar working with Professor Emmanuel Candes at Stanford University. Prior to this, I obtained my PhD degree from Electrical Engineering, Columbia University in 2016, working with Professor John Wright.
Research Interests: foundations of machine learning, data sciences, and numerical optimization, with application to computer vision, signal/image processing, and computational imaging. See my [CV].

- Paper release: our new paper Dual-Reference Design for Holographic Coherent Diffraction Imaging is on arXiv. We show that augmenting both the pinhole and block references in holographic CDI can combine the best parts of both! (Feb 07, 2019)
- Paper release: full version of the paper Holographic Phase Retrieval and Optimal Reference Design on arXiv. We show how the difficult Fourier phase retrieval problem can be substantially simplified and robustly solved in practical CDI (i.e., Coherent Diffraction Imaging) setting, with a simple augmented reference.

- Visiting Georgia Institute of Technology (Nov 29–30, 2018)
- Talk at SINE Seminar Coordinated Science Laboratory, UIUC (Nov 05, 2018)
- Paper release: full version of the paper Subgradient Descent Learns Orthogonal Dictionaries on arXiv. We show that nonconvexity and nonsmoothness can be tackled together rigorously on practical problems. (Oct 25 2018)
