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.[1][2][3]

Education

In 1965, Rubinstein matriculated (i.e. graduated) 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.(Honours) 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.[4]

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 (namely 0-efficient and 1-efficient triangulations), 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
gollark: My DB-using projects include all migration capability too, if sometimes limited to a bunch of `CREATE TABLE IF NOT EXISTS` calls, but if I ever *needed* it I would just make them able to call some functions to migrate the rows.
gollark: Well, yes, unless you write an extension for it, but no fixed length ones, and I can just do complex stuff in the program.
gollark: You're right, maybe just preinstall a rootkit on all the systems with databases?
gollark: I guess my decision to use SQLite and PostgreSQL for basically everything ever, as they don't have these constraints, was good then.
gollark: Well, there's a simple solution:- find an exploit in MySQL query parsing/execution allowing external code execution- make it execute a binary you craft which causes it to send a HTTP request to your PHP code- that PHP code then fixes the database
