Hu Ding

I join the department of computer science and engineering at Michigan State University in 2016, as a tenure-track assistant professor. I got my Ph.D under supervision of Dr. Jinhui Xu,  in the Department of Computer Science and Engineering, State University of New York at Buffalo, in Sep 2015. I received my bachelor degree in Mathematics from Sun Yat-Sen (Zhong Shan) University in Jun 2009. My research centers around designing efficient geometric algorithms and emphasizes both theoretical development and their applications in real world.

I am looking for motivated Ph.D students who are interested in theory/algorithms starting from Fall 2017

Recent news:

1. Our recent paper in Human Molecular Genetics is recommended by F1000Prime as an Article of Special Significance to the research on 3D pattern of chromosome territories!
2. One paper is accepted to AAAI 2017, two papers are accepted to WADS 2017.
3. Gave a seminar talk at SUNY at Buffalo, Novel Geometric Techniques for Reducing Communication Cost in Distributed Data Analysis, April 17, 2017.
4. Gave one hour featured talk at Simons Center, SUNY at Stony Brook, Simplex Lemma And The Applications in Data Analysis, April 20, 2017.
5. I teach CSE891 Selected Topics: Geometric Algorithms for Machine Learning in Spring 2017.

We study the popular k-means clustering problem in the environment that the dimensions are distributed, and our algorithmic framework matches the approximation ratio by the recent [Cohen et al. STOC 2015], but has a much lower communication complexity.

Journal Papers:

p.s., I have published a couple of papers in biological journals due to the collaboration with Dr. Ronald Berezney and his group, where we develop algorithms to discover the interaction patterns and topology structures of chromosome territories.
