Background

For my undergraduate degree I studied Physics at the University of Warwick, graduating in 2022 with 1st class honours (MPhys Physics). My final year project supervisor was Dr John Marshall and the title of the project was "Classification of neutrino-induced particles, and characterisation of showers at DUNE".

Undergraduate Research

During the course of my undergraduate studies, I undertook three summer research projects, each support by a Warwick Undergraduate Research Support Scheme (URSS)Link opens in a new windowLink opens in a new window bursary.

Phase Transitions and Dielectric Properties of Nano-confined Water (Jul 2019 - Aug 2019)

My first year summer project supervisor was Dr Jon Duffy and the project involved operating a liquid nitrogen cooled cryostat connected to a PID temperature control system to measure the dielectric properties of a porous glass medium saturated with water.

Monte Carlo Study of Equilibrium State of NiAl Crystal (Jul 2020 - Aug 2020)

My second year summer project supervisor was Dr Peter Brommer and the project involved using Python alongside LAMMPS to generate data to investigate transition bands within NiAl.

Deformation of Droplets at High Speed (Jul 2021 - Aug 2021)

My third year summer project supervisor was Dr Radu Cimpeanu and involved solving the Navier-Stokes equation for a Poiseuille flow with Basilisk implemented in C. The project involved regular meetings with a computational fluid dynamics group to discuss progress and techniques.

Research Interests

I am now in the third year of the HetSys programme, working under the supervision of Prof David QuigleyLink opens in a new windowLink opens in a new window. We study the use of machine learning models to predict the committor for physical systems. Currently my research efforts are focussed on predicting the committor for the 2D Ising model with a constant magnetic field as a proof of concept. The next stage of the project will likely involve moving to off lattice 3D systems.

Side Projects

I am working with Dr Christopher Woodgate in order to study high-entropy alloys (HEAs), in particular focussing on sampling methods. My role involves implementing Transition Matrix Monte Carlo in order to be able to extract the density of states for a given HEA and be able to compute other values of interest such as the heat capacity and entropy across a temperature range. From those values one can find the temperature at which phase transitions occur.
