That time of year again! If you'd like an example of job apps in academia or industry, here's a good resource. If you got a job in industry or academia in the last few years, please consider adding yours! github.com/RILAB/statem...
Mohg's spear is easy mode
This was an insane idea, and this paper would not have existed if the Center for Complex Systems hadn't paired a sharp physics student with my biology lab. Interdisciplinary science wins again. Great working with @jdyeakel.bsky.social and others, as usual.
Finally, groups are fragile to the addition of new (competent) members, suggesting disruptions to the learned interaction structure reduces collective performance.
Interestingly, agents all learn different strategies, spanning a 3D manifold of behavioral strategies. These strategies are defined by tradeoffs in exploratory search, energy conservation, and interception rules
We find that agents learn remarkable coordinated behaviors, from prey flanking and interception, to distributed follow-the-leader dynamics, to aborting costly pursuits.
We ask what happens in agent-based food webs when predators deploy a deep neutral network as their decision-making apparatus. Agents take in sensory information and translate these to actions.
New paper led by my (now former!) PhD student, Dr. Stephen Hoover, showing some amazing applications of AI and reinforcement learning to food web ecology. A 🧵...
It is one of the great joys in my life to share my lab's first successful PhD defense. Congratulations, Dr. Hoover!
I really wish I could make this 🥲
My first PhD student is defending in 2 weeks and he just showed me his beamer slide deck 👉🏽😎👉🏽
If you like matrices + microbes, have I got the paper for you. Work with @janamassing.bsky.social, @jdyeakel.bsky.social, and @thilogross.bsky.social out today in @royalsocietypublishing.org! We study dynamics of cooperative bacteria without specifying a conventional model: doi.org/10.1098/rsif...
Yes HORs are good, the loss of generalizability is what I was referring to 😎👍🏽
Yes, I meant the extra complicatedness is not good! Not that we should ignore HORs
This should be an important result for ecology. Higher-order interactions are becoming increasingly popular to study, but that appears to be... not good
New on the arxiv:
“Graphs are maximally expressive for higher-order interactions”
arxiv.org/abs/2602.16937
We clarify central misconceptions in the recent literature on "higher-order networks".
w/ @piratepeel.bsky.social , @manlius.bsky.social, and @thilogross.bsky.social

Really cool, can't wait to read! This is in the process of happening in ecology, looking forward to citing this paper a bunch.
Bring together a group of researchers to collaborate at NITMB!
Our Focused Research Group Awards program welcomes small groups from multiple institutions to gather at NITMB to focus intently on independent, ambitious joint research projects

Paper alert! Our study about functional motifs is out in PNAS. We use food webs as an example to discuss how small subgraphs drive the dynamics in complex systems. While motifs that determine overall stability are rare, when it comes to reactivity, we show that small groups dominate system behavior.
New paper with @mhab.bsky.social @jdyeakel.bsky.social and @thilogross.bsky.social out now in @pnas.org! We show when and why you can know something about an entire network, just by knowing the behavior of it's building blocks: doi.org/10.1073/pnas...
Very cool-looking paper! Pseudo-persistence through reactivity.
NSF is open again!
A few comments:
*Please be patient.
During a shutdown NSF employees cannot open computers or respond to emails.
*Merit review will continue. However panels won’t resume until after Dec 8th.
*POs remain excited and committed to advancing science and the scientific workforce.
We are doing spatial patterns in class tomorrow. So please enjoy my simulation of Pokemon battles on a lattice. Pokemon attack a random neighbor and winners are based on the game's hierarchy (water > fire > ice ...). Some amazing spatial patterns emerging from 7-way rock-paper-scissors!

You've heard of Bacon numbers, Erdos numbers. Who is it for ecology? I bet most have a Levin number < 3.
Our paper made the cover of Trends in Microbiology! doi.org/10.1016/j.ti...
