Marty Ross is a mathematical bum. At the age of 2, he ran away from America to join the circus. After some controversy involving an elephant, he returned to America to do his PhD on minimal surfaces at Stanford University. After a stint at Rice University, he came back to Australia. Since then, he has wandered from Maths Department to Maths Department, aimless but happy.
