Incoming PhD Student, Computer Science — EPFL

Hello! My goal is to make it easier for programmers to build reliable systems. I hope to contribute to this through research on formal methods and programming languages. Though my interest is in the field broadly, I focus mostly on its application to networking.

Algebraic Routing

Algebraic Routing

Research at the University of Cambridge, supervised by Prof. Timothy Griffin. It presents new results on the asynchronous behaviour of routing protocols, and formalises them in Agda. It builds on decades of work in algebraic routing by Prof Timothy Griffin and PhD research by Dr Matthew Daggitt, where they use algebraic structures to reason about network protocols. My bachelor thesis laid the foundation in a synchronous setting, and my master thesis extended it to the asynchronous nature of real-world routing.

CV

I'm an incoming PhD student in Computer Science at EPFL (2026 - now).

Prior to returning to academia I was a software engineer and team lead at IMC Trading (2020 - 2026).

I earned my bachelor and master degrees in Computer Science at the University of Cambridge, where I mostly focussed on theoretical computer science and where I developed my passion for formal methods, programming languages and research (2016 - 2020).
