Dr Mark Williamson

Proleptic lecturer


I am a Proleptic lecturer in the Department of Mathematics and Global Systems Institute at the University of Exeter.

My research is broadly in climate and climate change. I am a theoretical physicist by training and try to use the analytical techniques and models common to theoretical physics to understand climate models, the Earth itself and even sometimes other planet's climates. I've worked with a range of climate models from simple and idealized to full complexity and on quantum information theory and foundations of quantum mechanics. My main present interests are tipping points in the climate system and the use of emergent constraints to reduce uncertainty in future climate projections. 

Research specialisms

  • Earth system modelling,
  • Emergent constraints,
  • Tipping points,
  • Quantum information and foundations.
