Welcome to Stellenbosch University

Prof Gerhard Venter

Professor: Mechanics Division

In November 2006, Prof Gerhard Venter was appointed as an Associate Professor in the Mechanics Division of the Department of Mechanical and Mechatronic Engineering. He was promoted to full Professor in June 2008.

He did his PhD on non-dimensional response surfaces for structural optimization with uncertainty. His fields of speciality are in numerical design optimization: General-purpose, structural and multidisciplinary optimization. Prof Venter is currently doing research on particle swarm optimization, piecewise approximations, design of experiments, minimizing manufacturing cost, parallel computing and approximation methods.
