Kearn Grisdale

Postdoctoral Research Assistant

I am researcher in the HARMONI group, within in Astrophysics subdepartment. After completing my PhD in May 2017 I completed a short Postdoctoral research position at the University of Surrey, followed by the Balzan Research fellowship at the University of Oxford, before beginning my current post.

My research with the HARMONI group involves is focused on making predictions about what HARMONI will be able to tell us about the galaxies and their stars are range of different redshifts. I achieve this through the use of high resolution hydrodynamical simulations of the Universe. Currently I am making extensive use of the NewHorizon cosmological simulation as well as my own isolated galaxies simulations.

My primary research interests include:

  • The role of stars in the evolution of galaxies.
  • Modelling and understanding the processes of star formation
  • Source of turbulence in the ISM
  • Comparing simulations and observations in consistent ways

Below are links to slides and in some cases videos of my most recent talks:

2018 IAU Symposium 327: Early Science with ELTs

2018 Santa Cruz Galaxy Workshop

Below are several movies which show the how my simulations evolve with time.
