Daniel S. Sage

Daniel S. Sage is a Professor in the Department of Mathematics at Louisiana State University, Baton Rouge. He earned his A.B. summa cum laude in Mathematics from Harvard University (1989), followed by S.M. (1990) and Ph.D. (1995) in Mathematics from the University of Chicago. His professional experience includes positions at the University of Utah, Institute for Advanced Study (Princeton), Max Planck Institute for Mathematics, University of Paris VII, University of Zurich, Courant Institute, and Mathematical Sciences Research Institute.

His research focuses on:

• The geometric Langlands program
• Geometric and combinatorial methods in representation theory
• Hopf algebras and quantum groups
• Composite materials and the G-closure problem

His recent publications (2011-2020) show strong emphasis on geometric representation theory, moduli spaces, quantum algebras, and differential systems, with consistent applications of algebraic geometry to problems in mathematical physics and Lie theory.

Awards and Honors:

• Ethel Raybould Visiting Fellow, University of Queensland (2017)
