The Clay Research Award, presented in 2016, recognized Bernd Siebert for his foundational contributions to the theory of Gromov–Witten invariants. Born in 1964 in Wilmersdorf, Germany, he has established a career as a mathematician and university teacher, shaping modern research in algebraic geometry through international collaboration and advanced theoretical frameworks that bridge complex and tropical geometry.
Academic Formation and Early Research
Siebert initiated his mathematical training in 1984 at the University of Erlangen before transferring to the University of Bonn in 1986. By 1987, he moved to the University of Göttingen, where he completed his Diplom under the supervision of Hans Grauert. Following this, he served as Grauert’s assistant and doctoral student, earning his PhD in 1992 with a dissertation focusing on Faserzykelräume, geometrische Plattifikation und meromorphe Äquivalenzrelationen. He secured his habilitation in Bochum in 1998, with a thesis centered on Gromov–Witten invariants for general symplectic manifolds.

Starting in 2000, Siebert spent two years as a DFG-Heisenberg Fellow at the University of Paris VI and VII. His career shifted toward professional academic appointments in 2002, when he accepted a professorship at the Albert-Ludwigs-Universität Freiburg. During this period, he initiated a significant collaborative program with Mark Gross. Their joint research, utilizing insights from logarithmic geometry, produced a series of influential papers relating to mirror symmetry and tropical geometry. This partnership resulted in an invitation to speak at the 2014 International Congress of Mathematics in Seoul, where they addressed local mirror symmetry in the tropics.
Institutional Appointments and Recent Tenure
In 2008, Siebert transitioned to the Universität Hamburg, where he later became the head of the Graduiertenkolleg Mathematics Inspired by String Theory and QFT in 2011. His career expanded further in 2018 when he joined the University of Texas at Austin as a professor of mathematics. At this institution, he holds the Sid W. Richardson Foundation Regents Chair in Mathematics #4. His scholarly output remains extensive, including co-authored works in major journals such as the Journal of the American Mathematical Society and Annals of Mathematics, consistently advancing the understanding of toric degenerations and Lefschetz fibrations.
