Jeffrey Brock

Jeffrey F. Brock is the Zhao and Ji Professor of Mathematics and Dean of the School of Engineering & Applied Science at Yale University. He also serves as the inaugural Dean of Science in Yale's Faculty of Arts and Sciences. His research focuses on low-dimensional geometry and topology, particularly hyperbolic geometry and its applications to data science. He has held leadership roles including Chair of Brown University's Mathematics Department (2013–2017) and founding Director of Brown’s Data Science Initiative (2016).

• Roles: Dean of Engineering, Mathematics Professor
• Key Affiliations: Yale University, Brown University

Education: B.S. from Yale University, Ph.D. in Mathematics from U.C. Berkeley (under Curtis McMullen). Postdoctoral positions at Stanford and University of Chicago. Extensive academic leadership experience, including administrative roles at both Brown and Yale.

Research Interests: Hyperbolic 3-manifolds, Teichmüller theory, geometric structures in data science. Notable contributions include geometric classification of hyperbolic 3-manifolds (with R. Canary and Y. Minsky) and advancing topological methods for analyzing complex data sets.

Publications: Over 40 peer-reviewed articles, including foundational work on the ending lamination conjecture and Weil-Petersson geometry. Recent work applies geometric methods to machine learning and medical imaging.

Awards: John Simon Guggenheim Fellowship (2008), Fellow of the American Mathematical Society (2017).

Labs/Initiatives: Brown’s Data Science Initiative, geometric and topological data analysis projects.
