Welcome to my home page at the University of Zurich. I am a post-doc in Ravit Helled's group at the Institute for Computational Science, studying the assembly of planetary systems embedded in protoplanetary discs, as well as a variety of numerical techniques and dynamics. I previously completed my PhD at the University of Leicester under the supervision of Dr. Richard Alexander. I am currently using a combination of N-body and viscous accretion disc modelling techniques to gain insight into the observed distribution of exo-planets. You can find me on twitter here. If you are looking for my exoplanet visualisation video, you can see the updated 2021 version below.

If you will look closely in the background you will observe a toy N-body integrator, running in real-time, written in Javascript and rendering to a HTML 5 canvas. This is currently actively modelling the gravitational interaction between 3 bodies, which are trapped in a figure-of-8 orbit with one another. Please examine the control options at the bottom of this page to interact with this simulation! If you're interested in going further down the browser-simulation rabbit hole, I've also made some preliminary progress on a browser-based SPH (Smoothed Particle Hydrodynamics) code, written in DART. You can see a test simulation of a gas cloud falling onto a binary here.
