Proc Natl Acad Sci U S A
. 2024 Jul;
121(32):e2318805121.
PMID: 39083417
How do we capture the breadth of behavior in animal movement, from rapid body twitches to aging? Using high-resolution videos of the nematode worm , we show that a single...

Chaos
. 2023 Mar;
33(2):023136.
PMID: 36859220
Isolating slower dynamics from fast fluctuations has proven remarkably powerful, but how do we proceed from partial observations of dynamical systems for which we lack underlying equations? Here, we construct...

Lee R, Stephens G, Kuhn B
Front Behav Neurosci
. 2022 Jun;
16:854486.
PMID: 35685272
While stress reactions can emerge long after the triggering event, it remains elusive how they emerge after a protracted, seemingly stress-free period during which stress incubates. Here, we study the...

PLoS Comput Biol
. 2021 Apr;
17(4):e1008914.
PMID: 33905413
An important model system for understanding genes, neurons and behavior, the nematode worm C. elegans naturally moves through a variety of complex postures, for which estimation from video data is...

Nguyen D, Iuzzolino M, Mankel A, Bozek K, Stephens G, Peleg O
Proc Natl Acad Sci U S A
. 2021 Mar;
118(13).
PMID: 33758099
Honeybee swarms are a landmark example of collective behavior. To become a coherent swarm, bees locate their queen by tracking her pheromones. But how can distant individuals exploit these chemical...

Nat Commun
. 2021 Mar;
12(1):1733.
PMID: 33741938
From cells in tissue, to bird flocks, to human crowds, living systems display a stunning variety of collective behaviors. Yet quantifying such phenomena first requires tracking a significant fraction of...

Kok R, Hebert L, Huelsz-Prince G, Goos Y, Zheng X, Bozek K, et al.
PLoS One
. 2020 Oct;
15(10):e0240802.
PMID: 33091031
Time-lapse microscopy is routinely used to follow cells within organoids, allowing direct study of division and differentiation patterns. There is an increasing interest in cell tracking in organoids, which makes...

Nat Commun
. 2020 Feb;
11(1):975.
PMID: 32080202
The reliable detection of environmental molecules in the presence of noise is an important cellular function, yet the underlying computational mechanisms are not well understood. We introduce a model of...

J R Soc Interface
. 2019 Aug;
16(157):20190174.
PMID: 31455164
A quantitative understanding of organism-level behaviour requires predictive models that can capture the richness of behavioural phenotypes, yet are simple enough to connect with underlying mechanistic processes. Here, we investigate...
