# About Jeffrey F. Brock

**Jeffrey Brock** is Professor of
Mathematics and Dean of Science (January 2019) at Yale
University. His research focuses on low dimensional geometry
and topology, particularly hyperbolic geometry. His work
William Thurston’s program to
understand *hyperbolic 3-manifolds* led to their
geometric classification in joint work with R. Canary and
Y. Minsky. More recently, he has worked to advance geometric
and topological methods in analysis of large, complex data
sets. He was an undergraduate at Yale, and obtained his
Ph.D. at U.C. Berkeley, after which he held positions at
Stanford and U. Chicago, before moving to the Brown
University Math Department, which he Chaired from 2013 to
2017. In 2016 he served as founding Director of
Brown’s Data Science Initiative. He moved to Yale in
2018, where he is now Professor of Mathematics and the
inaugural Dean of Science. He was a Guggenheim
Fellow in 2008 and was recently elected Fellow of the
American Mathematical Society.

**Jeffrey Brock** is Professor of
Mathematics and Dean of Science (January 2019) at Yale
University. His research focuses on low-dimensional geometry
and topology, particularly on spaces with hyperbolic
geometry or negative curvature. His joint work with
R. Canary and Y. Minsky resulted in a solution to
the *ending lamination conjecture* of W. Thurston,
resulting in the geometric classification theorem for
hyperbolic 3-dimensional manifolds that are topologically
finite. More recently, he has worked to understand
applications of geometry and topology to the structure of
massive and complex data sets and the risks and implications
of the increasing use of “black box” algorithms
in science and society.

He received his undergraduate degree in mathematics at Yale University and his Ph.D. in mathematics from U.C. Berkeley, where he studied under Curtis McMullen. After holding postdoctoral positions at Stanford University and the University of Chicago, he came to Brown as an associate professor. He was awarded the Donald D. Harrington Faculty Fellowship to visit the University of Texas, and has had continuous National Science Foundation support since receiving his Ph.D. In 2008 he was awarded a John S. Guggenheim Foundation Fellowship, and he was recently elected Fellow of the American Mathematical Society.

He was chair of the Mathematics Department at Brown from 2013-2017 and was the founding Director of Brown’s Data Science Initiative (dsi.brown.edu) launched in 2016. He was also the lead PI on Brown’s NSF TRIPODS Institute grant, to advance Transdisciplinary Research In Principles of Data Science.

He moved to Yale in 2018, where began as Professor of Mathematics. He will assume the role of Dean of Science in January 2019, overseeing the Science Division of Yale's Faculty of Arts and Sciences.

He maintains an active interest in music performance; he was the founding bassist of the Vijay Iyer Trio, recording on Iyer’s first two CDs, Memorophilia and Architextures. He and his wife Sarah live in Hamden, CT, with their two boys Elliot and Sam and their daughter Nora.
