Summary

  • πŸ”­ I am an astrophysicist studying the formation of the first stars, black holes and galaxies in the Universe with the largest telescopes on Earth and in space.
  • πŸ§‘β€πŸ’» Currently, I am a postdoctoral research fellow (DAWN Fellow) at the Cosmic Dawn Center, affiliated with the Niels Bohr Institute at the University of Copenhagen. Previously, I was part of the Cavendish Laboratory, University of Cambridge, working with Roberto Maiolino and Sandro Tacchella within the Kavli Institute for Cosmology. I completed my PhD at Sidney Sussex College, supervised by Renske Smit and Roberto Maiolino.
  • 🌌 My research interests revolve around galaxy formation and evolution in the early Universe: how the first stars and galaxies were formed, how they for the first time synthesised elements heavier than helium, and how they subsequently brought about the Reionisation of the Universe, a major phase transition that turned the neutral Universe back to a (mostly) ionised state.
