About Me

I am an incoming Senior Machine Learning Scientist at Visa, where I will be working on fraud detection and prevention using machine learning. Before that, I was a Research Fellow at the University of Southampton, where I applied machine learning techniques to maritime engineering challenges, collaborating with industry partners to optimise car carrier designs through estimating wave-induced resistance.

My Ph.D. research investigated how autonomous agents develop languages from scratch, with a focus on temporal dynamics in those languages. My work examining these temporal relationships in interpretable emergent communication has been published in leading conferences including NeurIPS and ICLR. Since 2025, I have also been a reviewer for NeurIPS, where I try to avoid becoming Reviewer 2.
