What you'll do
- Creating problems
- Solving problems
- Reviewing completed work
- Auditing completed work
- Writing reasoning for physics research
What you need
- Published work on one of the specific phenomena: Einstein-Cartan and Nieh-Yan axion inflation (perturbations and power spectrum, or FRW background dynamics), Dynamical Chern-Simons gravity in Palatini formalism, parity-violating inflation, or High-energy astrophysics: blazar jets, photohadronic emission, multimessenger constraints.
- Published work demonstrating at least one of the following families: First-order gravity, Topological terms in gravity, Cosmological perturbation theory, Numerical cosmology, or Astroparticle modelling.
- A verifiable publication record, ideally from the last five years.
- First author strongly preferred on publications.
- Sign-convention discipline in work.
- Working proficiency with LaTeX, Python, SymPy and Jupyter.
- English at B2 or above, including written reasoning.
Nice to have
- Familiarity with an agentic coding extension in VS Code.
