J. Hyam Rubinstein
Joachim Hyam Rubinstein FAA an Australian mathematician specialising in low-dimensional topology, serving as a professor in the Department of Mathematics and Statistics at the University of Melbourne.
He has spoken and written widely on the state of the mathematical sciences in Australia, with particular focus on the impacts of reduced Government spending for university mathematics departments.Education
In 1965, Rubinstein matriculated from Melbourne High School in Melbourne, Australia winning the maximum of four exhibitions. In 1969, he graduated from Monash University in Melbourne, with a B.Sc. degree in mathematics.
In 1974, Rubinstein received his Ph.D. from the University of California, Berkeley under the advisorship of John Stallings. His dissertation was on the topic of Isotopies of Incompressible Surfaces in Three Dimensional Manifolds.Research interests
His major contributions include results involving almost normal Heegaard splittings and the closely related joint work with Jon T. Pitts relating strongly irreducible Heegaard splittings to minimal surfaces, joint work with William Jaco on special triangulations of 3-manifolds, and joint work with Martin Scharlemann on the Rubinstein-Scharlemann graphic. He is a key figure in the algorithmic theory of 3-manifolds, and one of the initial developers of the Regina program, which implements his 3-sphere recognition algorithm.
His research interests also include: shortest networks applied to underground mine design, machine learning, learning theory, financial mathematics, and stock market trading systems.Honours
