Naomi Arnold

I am Naomi Arnold, a postdoctoral research assistant at Northeastern University in London, within the NetSI institute since March 2023. Previously, I was a postdoctoral research assistant within the Networks group in the School of Electronic Engineering and Computer Science at Queen Mary University of London.

My main research focus is on large temporal networks and higher order networks. I am currently working on:

  • higher-order Markov modelling of path- or sequence-based data.
  • applying this to maritime data of shipping journeys.
  • the use of temporal motifs for understanding financial transaction networks and the actors within them.

As part of this, I am a developer for the Raphtory open-source software for the analysis of temporal graphs.

I also maintain the FETA (Framework for Evolving Topology Analysis) codebase with Richard Clegg, which can be used for generating graphs from different growth models, and for model selection (paper describing the background and process here).

Outside of work, I am a passionate (amateur) climber. I record my favourite climbs or projects on my Instagram.
