Danny Calegari, 2011

Danny M. C. Calegari (born 24 May 1972, Australia) was the Richard Merkin Professor of Mathematics at the California Institute of Technology, and is one of the recipients of the 2009 Clay Research Award for his work in geometric topology and geometric group theory. He has joined the faculty of the University of Chicago.

Education and early career

In 1994, Calegari received a B.A. in Mathematics from the University of Melbourne with honors. He received his Ph.D. in 2000 from the University of California, Berkeley under the joint supervision of Andrew Casson and William Thurston; his dissertation concerned foliations of three-dimensional manifolds.^[1]

From 2000–2002 he was Benjamin Peirce Assistant Professor at Harvard University, after which he joined the California Institute of Technology faculty; he became Merkin Professor in 2007.^[2] In 2012, he became a fellow of the American Mathematical Society.^[3]

Calegari is also an author of short fiction, published in Quadrant, Southerly, and Overland. His story A Green Light was a winner of a 1992 The Age Short Story Award.^[4]
