Where does the life-death boundary come from, and how will a cell's dynamics unfold relative to it? Myself, Eran Agmon, and Randy Beer argue for a theory of cellular viability, with new global organizing principles for cell fate.

A shot I got manipulating the light passing through a soil sample at 250x magnification 🙂

As I watched a small patch of snow melt on my microscope slide, I was able to manipulate the light to get some really beautiful structure. Editing the colors and overlaying some effects gave this picture, which I'm quite happy with 🙂

Some debris from plants and cells found in a water sample, made to look like they're in outer space

Spider plant leaf, post processing to improve contrast 🙂

Rearranged the house, so it only feels right to pick a new selection of books to go behind the desk 🙂

It was an honor to get to present Viability Space Decomposition at the Theoretical and Experimental Approaches to Goal-Directed Behavior Workshop at BCAM in Bilbao. It was amazing to hear multiple people discuss how to tackle the viability of living systems. I feel inspired.

Day 4 of 7 for no context black and white photos from my life, challenged by @smellosopher.bsky.social. I'm quite fond of this one.

Day 3 of 7 for the no context black and white photos challenge.

Day 2 of 7 🙂

@smellosopher.bsky.social challenged me to do the challenge for 7 days, 7 black and white photos with no humans or explanations. Here's day 1. I can't think of who I should challenge, so I'll leave it as an open invitation 🙂

Was purging my digital files when I came across the ending note of an undergrad paper... I had forgotten I was doing all of this because of a caffeine-dependency fueled vendetta

This afternoon I recreated one of my favorite output spaces for a 2N continuous time recurrent neural network 🙂 magenta and cyan are nullclines. Blue dots are stable equilibria, red are unstable, and green are saddle nodes. Blue and red branches are saddle manifolds and carve the basins
