Is agency an essential concept for the effective description of life, e.g at the cellular scale? I am sympathetic, as I showed how it arises quite naturally in stochastic systems. See my Phys Rev E paper arxiv.org/abs/2503.15670 Much more to come on this .. !

Why are living things different from nonliving? In this piece for @quantamagazine.bsky.social I argue that it is because they are purposive and goal-directed: a capacity we can productively characterize as agency. www.quantamagazine.org/is-life-just...

A new paper from the lab! We use MEG and a "local/global" design in the language domain to ask whether the transitions between words in a sentence are encoded by a shallow transition-probability mechanism, in parallel to a tree-based syntactic mechanism. www.sciencedirect.com/science/arti...

Disentangling hierarchical and sequential computations during sentence processing

Sentences in natural language have a hierarchical structure that can be described in terms of nested trees. To compose sentence meaning, the human bra…

The word “model” hides two different ideas. Some models simplify reality to isolate a mechanism. Others predict universal properties shared by many systems. The renormalization group revealed the second possibility, and explains why simple models can describe Nature at all.

Noise equals control

Stochastic systems have a control-theoretic interpretation in which noise plays the role of control. In the weak-noise limit, relevant at low temperatures or in large populations, this leads to a prec...

I'm very excited about this virtual talk, tomorrow at 11am ET, and open to everyone! I will explain precisely how and why agency is part of Nature, and illustrate the idea with some examples from biology and beyond. No complex mathematics.
