After an incredible few years, my time at the AEI has come to an end. I’m grateful for the lovely memories and collaborators I’ve had the privilege to work with.
I’m excited to start a new chapter as a Marie Sklodowska-Curie Postdoctoral Fellow at the University of Southampton.

I’m incredibly proud to be part of this and to have my simulations turn into the first publicly available scattering and dynamical capture waveforms!
Below is a plot I made for the Einstein Toolkit Blue Book (arXiv:2503.12263) showing the waveforms SXS:BBH:3999 (scatter) and SXS:BBH:4000 (capture).

Kevin De Bruyne is the greatest midfielder in premier league history. By a distance. City’s greatest ever player. We were privileged to witness his era. Not sure we’ll ever see someone with that talent again.

Edwin Hubble submitted his paper "A relation between distance and radial velocity among extra-galactic nebulae" #OTD in 1929.
It showed that "extra-galactic nebulae" were moving away from us with a velocity that increased linearly with distance. 🧪 🔭 ⚛️

It's been snowing in the UK and the road gritters are out in force, begging the question:
Have you ever wondered where that grit actually COMES from?
The answer is more magical, beautiful and fascinating than you probably realised.
