Kia Ora!

My name is Timothy (Charles) Andrews, a postdoctoral research fellow at the University of Michigan.

I was born in Croydon (outer London, United Kingdom), grew up in New Plymouth (New Zealand), studied my undergraduate degree in Auckland (New Zealand), completed a PhD in Mathematics at the University of Exeter (United Kingdom), and am currently living and researching in Ann Arbor (Michigan, United States). I sometimes get confused about what timezone/season I am in!

My current research group is the Atmospheric and Dynamics Modelling Group at the University of Michigan, headed by Professor Christiane Jablonowski. I am also a code developer for Gusto (Github, website) a toolbox for solving geophysical fluid equations using compatible finite elements.

P.S. Kia Ora is a Maori greeting we use in New Zealand.

Research Focuses:

• Numerical modelling of geophysical fluid equations, specifically:
  • Pseudospectral and compatible finite element methods
  • Quantification of timestepping error
  • The phase-averaged timestepping method
  • Parallel-in-time methods
• Evaluation of dynamical cores for Global Circulation Models (GCMs), primarily through idealised test cases
• Investigation and quantification of numerical diffusion in dynamical cores

Education:

• Doctor of Philosophy (PhD) in Mathematics (Geophysical and Astrophysical Fluid Dynamics) — University of Exeter (2020–2024)
• Bachelor of Engineering with First Class Honours, specialising in Engineering Science — University of Auckland (2016–2019)
