Temperature affects all biological rates, but how do we model its effects? Our 2-part review brings together modeling approaches from empirical curve fits to microscopic kinetics to network-level dynamics 🧵

Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

Just published in @science.org 🚀

By controlling how cells align, we show that living nematic tissues can be programmed to generate forces and fold into predictable 3D shapes.

A new platform for tissue engineering and the design of smart active materials! 🫆

How do pairs of DNA loci - such as enhancers and promoters - find each other inside the nucleus? 🤔

Most models assume the random forces driving locus motion are independent in space

New Perspective form Rory Maizels & me: "Gene regulatory networks: from correlative models to causal explanations"

Gene regulatory networks are supposed to give us mechanistic explanations of development, so why are we drowning in 'hairballs' of statistical correlations?
