Here is the solution video that Andrei posted for the monthly challenge. A fun video showing some interesting properties of the sums of random variables!

figure 1 from https://doi.org/10.1086/737588 describing (a) our conceptualisation of an evolutionary transition in individuality, (b) an interpretation of the traits that we consider in our mathematical model, and (c) a graphical representation of the population dynamics in the model.

Interested in host-symbiont interdependence, eukaryogenesis, and evolutionary transitions in individuality? my first paper just came out! With @gokhalecs.bsky.social and Pete Czuppon, we study when & how individuality emerges in a host-endosymbiont collective doi.org/10.1086/737588 a short thread🧵:

I think this poster could be substantially improved by swapping the New York Rangers logo for a logo from either the Texas Rangers or Rangers FC.

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.

The first speaker is @sebastianschreiber.bsky.social from UC Davis, who is giving a talk on the "Impacts of the Tempo and Mode of Environmental Fluctuations on Population Growth".

This afternoon, I am sitting in on part one of the #SMB2025 session on "Advances in Spatial Ecological and Epidemiological Modeling and Analysis", organized by Daozhou Gao (Cleveland State University) and Xingfu Zou (University of Western Ontario).

Slide presenting the motivation for the talk, highlighting the dynamics of political polarization.

The first talk is by Olivia Chu from Bryn Mawr College, who is gicing a talk on "Adaptive network models and the dynamics of political polarization and social activism".

#SMB2025

This morning at #SMB2025, I am sitting in on a minisymposium on Modeling Social and Political Ecosystems, featurong talks by Olivia Chu, Alexandria Volkening, and David Sabin-Miller.

I just got my supply of SMB baseball cards for the 2025-2026 academic year. They make great party favors for a mathematical biology course!

#SMB2025

I am looking forward to picking up more SMB base all cards at #SMB2025.

I am really enjoying this talk by Mark Lewis, which highlights a lot of really exciting work on nonlocal PDE motions in ecology and collective behavior. It is a particularly fitting talk for tje Okubo Award lecture, showcasing the exciting history of spatial models on biology.

A slide I presented in a mathematical biology talk featuring a screenshot of a Tweet by bob's burgers urbanist. The tweet features an image of a cartoon image from Bob's Burgers and the text "This kind of smart, walkable mixed-use urbanism is illegal to build in many American cities."

Because this visit lines up with the @smbmathbiology.bsky.social Annual Meeting in Edmonton, I may not be the only person in Edmonton that week who makes a reference to the @yhdistyminen.bsky.social Bob's Burgers urbanism meme!

Congratulations, @carlastaver.bsky.social!

I guess this is partly true. We had to have a day with an extra free period to be able to make it to Connecticut and back for lunch in high school. 😀

Exploring the Evolution of Altruistic Punishment with a PDE Model of Cultural Multilevel Selection - Bulletin of Mathematical Biology Two mechanisms that have been used to study the evolution of cooperative behavior are altruistic punishment, in which cooperative individuals pay additional costs to punish defection, and multilevel s...

It was fun to combine some of the ideas from the models of Luo and of Boyd et al in a PDE model for multilevel selection and the evolution of altruistic punishment, which was something I was able to explore in a recent paper.

YouTube video by SMTPB Reflections on Modeling and Theory in Population Biology: Joel Cohen

For “Reflections on the history of modeling and theory”, @sarperotto.bsky.social and I met with Joel Cohen. We learn how he navigated math and biology, the value of embracing ignorance, and what is a population. Or really, what _isn't_ a population: www.youtube.com/watch?v=RCt9...

The other paper is by Robert Boyd, Herbert Gintis, Samuel Bowles, and Peter Richerson, and studies the evolution of altruistic punishment by cultural multilevel selection with frequency-dependent group-level competition.

This paper focuses on a model of multilevel selection that combines ideas from two of my favorite papers. The first paper is by Shishi Luo, which describes a framework for describing selection at two levels using a nested Moran process.
