G’day

I am Zoe Wyatt, a Herchel Smith Postdoctoral Research Fellow at the Department of Pure Mathematics and Mathematical Statistics and a Junior Research Fellow at Darwin College, University of Cambridge.

My research lies at the intersection of general relativity, differential geometry and hyperbolic PDEs. I am very interested in studying PDEs derived from theories of higher dimensional gravity, string theory, particle physics and cosmology. My contact details are firstname.surname@maths.cam.ac.uk.

Other maths projects

  • I wrote a 2 page summary of my Kaluza-Klein paper for the UoE School of Maths Postgraduate Research Student Essay Prize.
  • In my first year MIGSAA project I showed the non-linear stability of n+1 dimensional Minkowski spacetime for n \geq 6 (up to some finer points regarding initial data).
  • In my Part III essay in 2014 I generalised the proof of local well-posedness of BSSN to high dimensions, n+1 for n \geq 3. This was actually not known before then.

In my spare time, I love bird-watching, cycling and reading. I also have a better half.
