Research interests

Coding theory, probabilities and message-passing algorithms. In particular, I have been looking at designing low-complexity message-passing algorithms for signal estimation (e.g. matrix sketching, multiple access channels).  From a more technical perspective, I’ve been interested in analysing message-passing algorithms on sparse and dense graphs.

Teaching activities

Supervisor for third-year courses 3F7 Information Theory & Coding and 3F4 Data Transmission

Demonstrator for 3F4 Data Transmission laboratory

Role and responsibilities

I completed my BA and MEng degrees at Cambridge with Distinction in June 2019. My MEng thesis was titled Efficient Sparse Principal Component Analysis for Low-rank Matrices using Linear Codes. From 2019 till now, I’ve been pursuing a PhD in coding theory. I’m currently in the fourth year of my PhD, aiming to graduate by mid-2024.
