Neil Lewis

Neil Lewis is a Researcher in the School of Physics and Astronomy at the University of Exeter. He focuses on Geophysical and Astrophysical Fluid Dynamics, particularly the mechanisms behind solar-like differential rotation in stellar convection zones and the dynamics of planetary atmospheres. His work bridges Earth's climate systems with exoplanetary and Solar System dynamics.

• Undergraduate: Mathematics (University of Exeter)
• DPhil: Atmospheric, Oceanic and Planetary Physics (University of Oxford)

Current research includes:

• Hydrodynamic vs. MHD routes to differential rotation in stellar convection zones
• Interaction between 'deep' and 'shallow' jets on Jupiter
• Bistability in GCM simulations of tidally-locked exoplanets
• Dynamics of persistent extreme weather events on Earth
• Arctic warming impacts on mid-latitude climate

His recent publications emphasize modeling and simulation techniques (Isca GCM, Dedalus) applied to exoplanetary atmospheres, Solar System dynamics, and Earth's climate. Key methods include eclipse mapping, shallow-water modeling, and numerical simulations of convection and atmospheric circulation.

Neil is a lead developer of the Isca General Circulation Model (GCM) framework for planetary atmospheres and uses the Dedalus framework for stellar magnetoconvection studies.
