Ding-Zhu Du (born May 21, 1948) is a Professor in the Department of Computer Science at The University of Texas at Dallas.[1] He has received public recognition when he solved two long-standing open problems on the Euclidean minimum Steiner trees,[2] the proof of Gilbert–Pollack conjecture on the Steiner ratio of the Euclidean plane, and the existence of a polynomial-time heuristic with a performance ratio bigger than the Steiner ratio.[3] The proof of Gilbert-Pollak's conjecture on Steiner ratios was later found to have gaps, thus leaving the problem unsolved.[4]

Education

[edit]

Ding-Zhu Du received his M.Sc in Operations Research from the Chinese Academy of Sciences in 1985. He received his Ph.D. in Mathematics with research area in Theoretical Computer Science from the University of California, Santa Barbara in 1984.[1]

Career

[edit]

Early in his career he solved two long-standing open problems on the Euclidean minimum Steiner trees, the proof of Gilbert-Pollak's conjecture on the Steiner ratio, and the existence of a polynomial-time heuristic with a performance ratio bigger than the Steiner ratio.[2]

He was Program Director for CISE/CCF, National Science Foundation, USA, 2002-2005,[5] Professor, Department of Computer Science, University of Minnesota, 1991-2005.[6] and Assistant Professor, Department of Mathematics, Massachusetts Institute of Technology, 1986-1987.

He has been active in research on Design and Analysis of Approximation Algorithm for 30 years. And over these years he has published 177 Journal articles, 60 conference and workshop papers, 22 editorship, 9 reference works and 11 informal publications.[7]
