Overview

Mark is involved in the EU project HELIX (High-End cLimate Impacts and eXtremes) which aims to assess the impacts of climate change above 2oC global warming (www.helixclimate.eu). He is looking at tipping points in the climate system in particular.

Broad research specialisms:

  • Earth system modelling,
  • Quantum information and foundations.

Qualifications

PhD, Theoretical Physics, Leeds, 2009.
MSc, Optics and Photonics, Imperial College London, 2002.
BSc Oceanography with Physics, Southampton, 2001.
