New preprint! "Identifying statistical indicators of temporal asymmetry using a data-driven approach" arxiv.org/abs/2511.15991 _Can we statistically distinguish the forward- versus reverse-time dynamics of a system from a finite time series?_ 👇

No one is talking about how amazing Photoshop's generative AI is going to be for science. A simple "improve correlation" prompt and say goodbye to p > 0.05!

New preprint! @olivercliff w/ @NaoTsuchiya @jlizier: "Unifying Pairwise Interactions in Complex Dynamics". Want to quantify the relationship between two time series? We compared over 249 pairwise dependence measures on >1000 multivariate time series 😮 arxiv.org/abs/2201.11941

Some of my time-series feature extraction art is now up on the walls of the @sydney_physics :) A great idea to add a bit more life and character to the building (@taraxmurphy 😊)

I'll be presenting an introduction to feature-based time-series analysis on 30th June, including some new interactive visualizations. There are some great speakers and tutorials in the line up: can register below 🙃⬇️ didvizandstats.org

Latest preprint: "Parameter Inference from a Non-stationary Unknown Process" (PINUP) We're really interested in the problem of inferring sources of non-stationary variation directly from measured time-series data. arxiv.org/abs/2407.08987… Quick summary 👇

New preprint! Why are long-range connectomic interactions in the cortex dominant in shaping dynamics in some experiments but apparently negligible in others? We (w/ Rishi M, @eli_j_muller) address this by studying a new hybrid model of cortical dynamics. arxiv.org/abs/2506.19800

Latest preprint by incredible @AnnieGBryant Multivariate time series are studied across neuroimaging (fMRI, MEG, …) but how can we best extract the most relevant dynamical patterns in a given dataset? FC (Pearson or alternative)? Local dynamics (fALFF or alternative)? Both??👇
