About me

I trained as an astrophysicist and spent several years modelling relativistic jets, fitting models to multi-wavelength data, and running large simulations on European HPC clusters. That work meant building my own tools, being careful about where errors came from, and making sure results could be reproduced.

Those habits carry over to data and software work: build something, check it against reality, and be clear about what it does and doesn't show.

Research, in one minute

I study energetic outflows from active galactic nuclei: supermassive black holes that launch relativistic jets across hundreds of thousands of light-years. The work combines magnetohydrodynamic simulations with multi-wavelength observations to understand how these jets produce the radiation we measure.

The method is general: build a physical model, work out what it predicts, compare with data, and write down what holds up and what doesn't.
