# About Jeffrey F. Brock

**Jeffrey Brock** is Professor of Mathematics at Brown University and Director of Brown’s Data Science Initiative. 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 settling in 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 was a Guggenheim Fellow in 2008 and was recently elected Fellow of the American Mathematical Society.

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

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 Barrington, RI, with their two boys Elliot and Sam and their daughter Nora.
