Hu Ding

I join the department of computer science and engineering at Michigan State University in 2016, as a tenure-track assistant professor. Prior that, I held a joint postdoc position of UC Berkeley and Tsinghua University from 2015 to 2016, which is titled as ``Simons-Berkeley Research Fellow". 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 algorithms for machine learning and pattern recognition, especially on large-scale, high dimensional, and noisy datasets. My research emphasizes both theoretical development and their applications in real world, e.g., big data, wireless sensor networks, computer vision, and biomedical image analysis. Please see my CV and research statement for details.

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