Job id: 138606. Salary: £45,031 per annum, including London Weighting Allowance.

Posted: 17 February 2026. Closing date: 24 February 2026.

Business unit: Natural, Mathematical & Engineering Sci. Department: Physics.

Contact details: Emilio Pisanty. emilio.pisanty@kcl.ac.uk

Location: Strand Campus. Category: Research.

About us

The role will take place within the Attosecond Quantum Physics Laboratory team, based in the Photonics & Nanotechnology group in the Physics Department and the Faculty of Natural, Mathematical and Engineering Sciences. AQPL is an open and inclusive team researching strong-field physics and ultrafast laser science, through both theoretical and experimental approaches. 

About the role

We are looking for a postdoctoral research associate to conduct theoretical research on attosecond and strong-field phenomena, using analytical approaches to study the response of atomic systems to high-intensity, strongly-polychromatic laser pulses. 

The candidate will extend our group’s existing research on implementing methods from Picard-Lefschetz theory into attosecond science: improving and extending our existing implementations, as well as applying them to existing and novel problem areas; the candidate will be expected to have existing expertise in the group’s existing activities. 

The candidate will report to Dr Emilio Pisanty, and the role will be conducted within the topic ‘Caustics and catastrophes in strong-field physics’, under the umbrella of the project ‘New frontiers of strong-field physics: vortices, catastrophes, and quantum electrodynamics’. 

This is a full time post, and you will be offered a fixed term contract until  31/03/2027.  

Research staff at King’s are entitled to at least 10 days per year (pro-rata) for professional development. This entitlement, from the Concordat to Support the Career Development of Researchers, applies to Postdocs, Research Assistants, Research and Teaching Technicians, Teaching Fellows and AEP equivalent up to and including grade 7. Visit the Centre for Research Staff Development for more information. 

About you

Essential criteria

1.       PhD awarded, or near completion*, in Physics or related areas 

2.       Extensive expertise on strong-field physics, catastrophe theory, and asymptotic approximation methods, in both analytical and numerical approaches 

3.       To have developed a creative and distinctive research vision within the field, which complements existing research within the department 

4.       Good presentational, organisational, and administrative skills, highly effective oral and written communication skills 

5.       Experience with theoretical atomic, molecular and optical physics

Desirable criteria

1.       Experience in applying for research funding, including financial support for research collaborations and conference attendance. 

2.       Experience in mentoring junior members of a research team.
