Education and 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. He was a University Professor of Pure Mathematics at the University of Cambridge in 2011–2012, and has been a Professor of Mathematics at the University of Chicago since 2012.[2]

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.[3]

Awards

Calegari was one of the recipients of the 2009 Clay Research Award for his solution to the Marden Tameness Conjecture and the Ahlfors Measure Conjecture.[4] In 2012, he became a Fellow of the American Mathematical Society.[5]

Personal life

Mathematician Frank Calegari is Danny Calegari's brother.[6]

gollark: Sometimes we construct arbitrarily recursive subuniverses and extract all possible energy from them.
gollark: This is HIGHLY renewable.
gollark: GTech™ produces power from communism-capitalism reactions in a previously described process.
gollark: Also, the sun will eventually do bad things.
gollark: Technically, solar panels have a finite lifespan and we can't make arbitrarily many from Earth resources.
