Projects


Asymptotic Decomposition of a Scalar Field in de Sitter Space

Jul–Aug 2024

Philippa Fawcett Internship | University of Cambridge
  • In July and August 2024, I undertook a two-month research project in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge, funded by the Philippa Fawcett Internship Programme.
  • My group's project was supervised by Dr Grigalius Taujanskas, and involved investigating the asymptotic decomposition of a charged scalar field in de Sitter space.

The Symbol Alphabet of One-Loop Feynman Integrals

May–Jun 2024
Hamilton Trust Internship | Trinity College Dublin
  • In May and June 2024, I participated in the Hamilton Trust Summer Mathematics Research Internship at Trinity College Dublin, in a group with Alexander Farren and Mikey Whelan.
  • Our project was supervised by Prof. Ruth Britto, and involved a study of the symbol alphabet of one-loop Feynman integrals in quantum field theory.

Coalgebra for Feynman Integrals

Sep 2023–Apr 2024
Capstone Project | Trinity College Dublin
  • During the 2023–2024 academic year, I completed my capstone project at Trinity College Dublin under the supervision of Prof. Ruth Britto.
  • My project was on the coalgebra structure of Feynman integrals, with a particular focus on the diagrammatic coaction.

Black Hole Entropy in String Theory

Jun–Jul 2023
Summer Studentship | Dublin Institute for Advanced Studies
  • In June and July 2023, I undertook a summer studentship in the School of Theoretical Physics at the Dublin Institute for Advanced Studies, which consisted of a group project in collaboration with three other students.
  • My group's project was supervised by Dr Aradhita Chattopadhyaya, and was based on the computation of black hole entropy via microstate counting of systems of 1/4 BPS dyons in type IIB string theory.

Electoral Redistricting of Ireland

May 2023
Real-World Mathematical Modelling Event | Trinity College Dublin
  • In May 2023, I participated in a three-day Mathematical Modelling Hackathon in Trinity College Dublin, in a group with Alexander Farren, Ben McGloin and Mikey Whelan.
  • We developed an evolutionary algorithm in Python designed to optimise the constituency boundaries of Ireland according to the criteria outlined in the Irish Constitution.

Solitons in 1+1 Dimensions

Nov 2023
Independent Project
  • A project in collaboration with Alexander Farren.
  • We generated animations of soliton dynamics in Mathematica, and produced an accompanying report outlining the basic theory of solitons in one spatial dimension.
