Postdoctoral Research Associate in Scattering Amplitudes; Redeployees

Please note:
This role is only open to redeployee applicants at City St George's in the first instance. Applications from individuals who are not redeployee applicants will not be considered at this time.

City St George’s, University of London is the University of business, practice and the professions and brings together the expertise and excellence of City, University of London and St George’s, University of London into one institution. The combined university is now one of the largest higher education destinations for London students, combining a breadth of disciplines across health, business, policy, law, creativity, communications, science and technology.

Our students are at the heart of everything that we do, and we are committed to supporting them to pursue their career and personal ambitions.

Our research is engaged, at the frontier of practice and has a positive impact on the world around us.

The Department of Mathematics conducts internationally excellent research across Representation Theory, Applied Mathematics and Theoretical Physics. Applications are invited for a one-year, full-time Postdoctoral Research Associate to join the Theoretical Physics group and work with Dr Andrea Guerrieri on the Royal Society-funded project S-matrix Bootstrap: a theoretical collider for particle physics. The postholder will benefit from the group’s broader research environment and collaborations across mathematical and theoretical physics.

The successful candidate will conduct original research in scattering amplitudes and related areas of theoretical and mathematical physics, developing innovative directions connected with the Royal Society-funded S-matrix Bootstrap project. They will contribute to the research activities of the Theoretical Physics group, support seminar and conference organisation, assist with research student supervision where appropriate, publish and present high-quality research, build external collaborations, and contribute positively to the Department’s collegial and interdisciplinary research culture.

Applicants should have a PhD awarded, or a PhD thesis submitted, in Theoretical Physics, Mathematics or a closely related discipline. They should demonstrate a strong research record and expertise in one or more relevant areas, including scattering amplitudes, S-matrix bootstrap, string theory, holography, integrability, gravitational physics, conformal field theory or related mathematical physics. The successful candidate will be able to work independently and collaboratively, communicate research effectively, and contribute positively to an inclusive research environment.

This post is offered on a permanent contract with an expected start date of 1 October 2026, reflecting the University’s commitment to providing greater stability for research staff. The role is funded through external research funding, which is currently confirmed for 12 months. Continued employment in this role will therefore be subject to the continuation or replacement of funding.
