Biography

  • 2023-ongoing Deputy Science Leader for Ice Dynamics and Palaeoclimate (IDP).
  • 2010- present Ice sheet modeller, British Antarctic Survey (first 2.5 years as part of EU ice2sea project).
  • 2005-09 PhD University of Glasgow, Department of Mathematics. Title: “Pattern formation and hydrogen production in suspensions of swimming green algae”. Date awarded: December, 2009.
  • BSc (First Class) in Mathematics, University College London, 2002-2005.

Research interests

I am an ice sheet modeller specialising in combining physics-based models with remote and field observations and machine learning. I am interested in improving projections of the future of Antarctica by bringing together data assimilation and a deeper understanding of important physical processes within the ice sheet and its interactions with the ocean and atmosphere. I am part of the International Thwaites Glacier Collaboration MELT project . Previously at BAS I have worked on NERC-funded projects to investigate the propagation of ocean-driven ice-shelf thinning and consequences for the interior of Antarctica and global sea level, and on model initialisation as part of  the EU funded ice2sea programme.

I am a mathematican by training and have previously worked on constructing, modifying and evaluating mathematical models of biological systems. Projects I have worked on include modelling the collective swimming behaviour of microorganisms and constructing a dynamical model of hydrogen production from green algae.
