Larry Guth (born 1977) is an American mathematician specializing in geometry, analysis, and combinatorics. He is a professor of mathematics at the Massachusetts Institute of Technology (MIT).
Education and Career
- Undergraduate: B.A. in Mathematics, Harvard University, 1999.
- Doctorate: Ph.D. in Mathematics, Massachusetts Institute of Technology, 2002. His dissertation, supervised by Shing‑Tung Yau, concerned “The Geometry of Systoles.”
- Postdoctoral Work: Institute for Advanced Study, Princeton, New Jersey (2002–2004).
- Academic Positions: Joined the faculty at MIT as an assistant professor in 2008, was promoted to associate professor in 2011, and became a full professor in 2014.
Research Contributions
Guth’s work is noted for applying combinatorial and algebraic methods to problems in geometry and analysis. Significant areas of impact include:
- Kakeya–type Problems: Development of polynomial partitioning techniques that advanced understanding of the Kakeya conjecture and related restriction problems in harmonic analysis.
- Systolic Geometry: Contributions to systolic inequalities, building on Gromov’s work and providing new quantitative bounds for Riemannian manifolds.
- Metric Geometry and Convexity: Results concerning volume estimates, isoperimetric inequalities, and the study of high‑dimensional convex bodies.
Honors and Awards
- Salem Prize (2009): Recognized for outstanding contributions to the field of harmonic analysis.
- MacArthur Fellowship (2015): Awarded the “genius grant” for his innovative research linking geometry, analysis, and combinatorics.
- Invited Speaker, International Congress of Mathematicians (ICM) 2014 (Seoul): Delivered a lecture on recent advances in geometric combinatorics.
