Maggie Chen

Particle physics DPhil student.

I am a third year DPhil student in the Oxford Exotics group. My main thesis topic is the ATLAS search for triple-Higgs production in the 6b final state, where I design analysis strategies and develop machine learning methods to separate signal from background.

I am also an active member of the ATLAS b-jet trigger group, both in algorithm development, in particular flavour-tagging algorithms, and operation during data-taking.

A main interest of mine is the development of machine learning techniques for high energy physics. My projects include kinematic regression using Deep Sets networks, exploring parametrised neural networks and graph neural networks for exotic particle searches.
