# About Jeffrey F. Brock

**Jeffrey Brock** is the Dean of the School
of Engineering & Applied Science, the Dean of Science in the
Faculty of Arts and Sciences, and the Zhao and Ji Professor
of Mathematics 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 the Dean of the School
of Engineering & Applied Science, the Dean of Science in the Faculty
of Arts and Sciences, and the Zhao and Ji Professor of Mathematics 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 became the inaugural Dean of Science in the Faculty of Arts and Sciences (FAS) in January 2019, overseeing the Science Division of Yale's FAS. In August 2019, he became the Dean of Yale's School of Engineering & Applied Science, adding the engineering departments to his purview.

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.
