Harvey Devereux

Welcome to my page!

I was a PhD student at MathSys working on collective motion in animal groups, looking at both modelling data (top-down) and generative modelling (bottom-up) approaches to active matter. I am now a Post-Doc at Queen Mary University of London, working on high-performance molecular dynamics software (DL_POLY)

Checkout my .js app below to play with a simulation of ("scared") Active Brownian Particles (a model I've used extensively in my research!) - harass them or leave them alone to observe Motility Induced Phase Separation (MIPS) in real time!

MIPS in Insects, MSc Individual Project, supervisors: Professor Matthew Turner, University of Warwick, Dr Shashi Thutupalli, NCBS Bangalore.

We study "Whirligig" beetles in motion on the surface of water, via laboratory data provided by Dr Shashi Thutupalli (NCBS, India).

The data was processed using a minimum-cost flow network formulation to reconstruct (improved) individual trajectories for each beetle (see below). Then we invesitgate the motility of the beetles in relation to the number density of observed, for which we recover a sharp transition of high motility and low density to low motility and high density, as well as results on beetle "separations". We aim to follow on from this work by modelling the system, investigating the behavioural strategies of the beetles using Inverse Reinforcement Learning, and conducting new experiments.
