High-Energy Theory

Welcome to the High-Energy Physics Theory Research Group (HEP-TH)

in the School of Mathematical and Physical Sciences of The University of Sheffield!

The HEP-TH Group is at the forefront of research in modern high-energy theoretical physics, focusing on topics such as: string theory, M/F-theory, (supersymmetric and superconformal) quantum field theories and their dualities, topological strings, (homological) mirror symmetry, string(y algebraic, differential, enumerative, and arithmetic) geometry, generalized symmetries, AdS/CFT, supersymmetric black hole microstate counting, integrable systems. 

See a more complete list of topics and open projects in the Research page.

We maintain close ties with both the Algebraic Geometry & Mathematical Physics (AGMP) and the Cosmology, Relativity, And Gravitation (CRAG) research groups at Sheffield (some of our members being also members of one or both of these).

We are also part of the STFC-funded Fundamental Physics UK virtual center (fpuk for short), which organizes and hosts remote and in-person events (e.g., the FPUK Edinburgh Festival 2025); and of the COST Action (CA22113) Fundamental Challenges in Theoretical Physics, which funds short visits to and by Action members.

We are currently funded by a EPSRC Fellowship Grant awarded to Andrea Brini, a Royal Society International Exchanges Grant and London Mathematical Society support grants awarded to Marco Fazzi, and a Leverhulme Trust International Professorship awarded to Albrecht Klemm.

To work with us, interested candidates should refer to the Open Positions page here and the Inspire/Jobs, AcademicJobsOnline, and MathJobs ads. We are part of the European Joint Postdoc Applications system hosted by KU Leuven (NB: this link might change for the upcoming fall 2025 application round).
