Modern-Day Oracles or Bullshit Machines: Introduction A free online humanities course about how to learn and work and thrive in an AI world.

Recently had the chance to hear @carlbergstrom.com on information foraging in the current space of LLMs.

He and @jevinwest.bsky.social have crafted a course that touches various facets of LLMs. Just finished reading through its 18 modules. Absolutely loved it!

Its very exciting to see this paper out in @behavecol.bsky.social. These conversations, expertly led by @delphinedemoor.bsky.social, have really shaped how I now think about working with social network data. Check out Delphine's thread to learn more!

Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n)

I'm really excited to see this paper by @fernpizza.bsky.social, @baym.lol, et al. This is a great model system for studying multilevel selection, and the experimental work builds nicely on cross-scale theoretical modeling approaches that I've enjoyed learning about over the past few years. ๐Ÿงต

This piece on infection history as a driver of individual heterogeneity in infection outcomes was fun to think about and to write with @chadisaadroy.bsky.social and Mike Boots. Also suggest that systems like #Drosophila can offer useful tools to tackle the epidemiological consequences.

Evolutionary Games: Mathematical Theory and Biological Insights

I am really happy to share that there will be a @nitmb.bsky.social workshop next year on mathematical and biological features of evolutionary game theory.

It was really fun to co-organize this workshop with Olivia Chu, Alex McAvoy, and @jplotkin.bsky.social.

Corina Tarnita and I have discussed the relation between theoretical ecology and evolutionary game theory since my sabbatical in 2022. Now the paper is out, doi.org/10.1073/pnas... Cooperation in nature may not be mysterious when there are growth differences- questioning the notion of cooperation.
