_Can we statistically distinguish the forward- versus reverse-time dynamics of a system from a finite time series?_ 👇
What kinds of dynamical structures have scientists developed models for?
Introducing the 1000×1000 collection: 1000 simulated time series × 1000 samples from 133 dynamical processes, from noise and chaos to hearts, brains and climate.

Rivers, pendulums and the thalamus: how the brain balances stable and flexible dynamics, and what changes when consciousness fades.
Our latest journey into how the thalamus is shaping cortical dynamics in @ScienceAdvances 🧵1/10

Interested in the principles shaping connectome architecture?
Check out our latest in @CellCellPress led by @_francisnormand w/ @jchrispang, @TrangCao2016,
J Cruddas, @m_gajwani, @Arshiya_San, @DrAlexHolmes, @StuartJOldham, & P Robinson.
We derive a simple model using geometric eigenmodes that can capture cortical connectome topology and topography of mouse, marmoset, macaque, chimp, and human connectomes, as mapped using diffusion MRI and tract-tracing.

Here's a mitochondrial "social network" (tracking encounters) emerging over time from their collective dynamics in a plant cell. This picture helps us understand their capacity to share and exchange biomolecules 🔬🌱🫂

The breath of comparison (of both methods and processes) also allowed us to demonstrate that all tested indices of irreversibility had weaknesses: i.e., we could always find an irreversibile process on which any given irreverisbility index will fail to detect irreversibility.
If you're interested in the statistics of time-irreversibility and how they can be used to capture novel, interpretable properties from real-world time series, take a look: arxiv.org/abs/2511.15991

I am looking to hire 1–2 postdocs for next year. Please feel free to reach out if interested in: (1) Inter-brain information translation & control (2) Characterizing brain states via thermodynamics & control theory (3) Comparing qualia structures across individuals and identifying their neural substrates.
Application details coming soon.
We have started recruiting many postdocs at Araya.
1. Scaling Laws for Brain Decoding
2. Computational models of Consciousness
3. Mathematical Theories of Consciousness
If you are interested, please take a look at this site and apply.
