"Senior Research Associate/Research Fellow in Foundations of Physics"

University of Bristol - Department of Philosophy

Location:	Bristol
Salary:	£44,746 to £58,225 per annum, Grade: J/K
Hours:	Full Time
Contract Type:	Permanent
Placed On:	2nd March 2026
Closes:	15th March 2026
Job Ref:	ACAD108484

The role

This is a four-year postdoctoral research position in foundations of physics. This position is for a post-doctoral researcher with expertise in philosophy of physics or theoretical physics and particular research interests in black hole physics and/or quantum cosmology. The role holder will be based in the Department of Philosophy at the University of Bristol and will work within the research team on the Leverhulme Trust project Explicating Singularity Resolution: From Black Holes to Quantum Cosmology, led by Dr Karim Thebault.

What will you be doing?

The successful candidate will work collaboratively with the project Principal Investigator (Karim Thébault) and Senior Project Advisor (Juliusz Doboszewski) towards the pursuit of the project objectives and the authorship of single and joint authored research articles.

The project's core objective is to provide a model-based explication of singularity resolution in modern theoretical physics. We will pursue this aim through three further sub-objectives:

• Explicate the concept of black hole singularity resolution in terms of necessary and sufficient criteria and relate these criteria to the cosmological case that was studied in previous work
• Use semi-classical analysis to connect quantum singularity resolution to the study of classical singularities in cosmology and black holes within the theorems of Penrose, Hawking and others.
• Articulate the connections between singularity resolution and heuristic principles relating to the arrow of time and chaotic cosmology.

The successful candidate will be expected to author and co-author research articles in theoretical physics, philosophy of physics or philosophy of science with a focus on sub-objectives 2 and 3.

You should apply if

• You have a PhD in Theoretical Physics or Philosophy of Physics
• You have at least an undergraduate degree (joint or single honours) in Mathematics or Physics
• You have advanced knowledge of general relativity
• You have interests in quantum cosmology and/or black hole physics
• You have interests in the philosophy and foundations of physics
