Danny Matthew Cornelius Calegari is a mathematician and, as of 2023, a professor of mathematics at the University of Chicago. His research interests include geometry, dynamical systems, low-dimensional topology, and geometric group theory.

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 2011 he was awarded a Royal Society Wolfson Research Merit Award,[5] and in 2012, he became a Fellow of the American Mathematical Society.[6] In 2012 he delivered the Namboodiri Lectures[7] at the University of Chicago, and in 2013 he delivered the Blumenthal Lectures[8] at Tel Aviv University.
