Ciarán joined ICHEC in May 2019. He completed a B.A (Mod). in Theoretical Physics before undertaking a M.Sc. in High Performance Computing, both at Trinity College Dublin. His M.Sc. thesis involved Monte Carlo simulations of lattice field theory algorithms wherein evolution of arbitrary-dimensional lattices was parallelised using MPI, equipped with an arbitrary-dimensional Halo exchange of both lattice sites and lattice links. Ciarán's undergraduate studies included a collaborative project on energy loss from public lighting. This involved analysis of ISS and VIIRS satellite images and public lighting databases using R and achieved a comparison between public and commercial lighting whilst also isolating buildings with the largest contribution to light pollution.
