Zhaolu (Tim) Liu

Hi, I’m Tim! I am 4th year PhD student in Mathematics at Imperial College London, where I am supervised by Professor Mauricio Barahona. During the first two years of my PhD, I worked as a research assistant in the EPSRC project Statistical Physics of Cognition and The Pissarides Review into the Future of Work and Wellbeing funded by Nuffield Foundation. Prior to this I did a MRes in Biomedical Research (Data Science stream) and a MSci in Mathematics also at Imperial College London.

My research project mainly deals with higher-order (beyond pairwise) interactions, it goes from formulating statistical tests and information-theoretic measures to detect higher-order behaviours to reconstructing higher-order systems such as hypergraphs and simplicial complexes using transformers.

On the side, I have also developed GAN-based super-resolution models for medical imaging such as mass spectrometry imaging, nuclear magnetic resonance spectroscopy and two-photon calcium imaging, and analysed 200 million UK job adverts using network clustering and LLM.
