Ding-Zhu Du is a prominent Professor in the Department of Computer Science at The University of Texas at Dallas, known for solving significant open problems in computational geometry, particularly regarding Euclidean minimum Steiner trees. He gained recognition for his proof related to the Gilbert–Pollack conjecture on the Steiner ratio and for developing a polynomial-time heuristic with a performance ratio exceeding the Steiner ratio. However, his proof on Gilbert-Pollak's conjecture was later found to have gaps, leaving that problem unresolved.
