New pre-print with @psmaldino.bsky.social on an agent-based model of propaganda in online spaces. Using the voter model from physics, we simulate networks with stubborn agents (zealots) who do not change their opinions, asking about their optimal positioning for influencing the network.

New paper where we explore how the dynamics of food webs can be explored when populations are ‘distilled’ to high and low states, or Boolean switches… Somehow this leads to a discussion involving Otodus megalodon :D nsojournals.onlinelibrary.wiley.com/doi/10.1002/...

So delighted to have worked with Drs Christine France and Julianne Sarancha on this project. With deer samples, we created isoscapes (Sr, O, and S) for the state of Virginia. Potentially hella useful for archaeology in the region. 🏺🧪 www.tandfonline.com/doi/full/10....

Does tidal marsh #restoration "work", if the goal is bringing back key species AND the trophic interactions that support them? A thousand stable isotope samples later, we have answers! 💯 work by PhD student Megan Pagliaro: esajournals.onlinelibrary.wiley.com/doi/10.1002/... #SanFrancisco #BayDelta

A landmark scientific workshop has identified 124 Important Shark and Ray Areas (ISRAs) across the European Atlantic, providing the first comprehensive map of critical habitats for threatened species such as Basking Shark, Tope, Spiny Dogfish, Sicklefin Devil Ray, and Angelshark.

Foraged this King Bolete (Porcini) yesterday! For dinner made a porcini pappardelle (pasta with and olive oil, parsley, and garlic sauce) and porcini carpaccio (raw porcini with parmesan and olive oil) 🤤

This made me really happy today

Can you name the four kinds of mushrooms my partner and I found foraging today? 🍄

The silvers are coming through!

I finally did it. My first chapter is FINALLY written and out for all to see. If you’ve attended my talks you 100% know what this is about. If you haven’t attended my talks, shark nostrils are more interesting than we thought. Enjoy! academic.oup.com/icb/advance-...

Grades turned in! First time being the instructor on record was challenging but really enjoyed it @ucmerced.bsky.social

I’m now in the desk rejection club! 🤩

Just submitted my favorite chapter of my dissertation (2/5 ✅)

Nature giving some good material for your next horror flick as per usual. Barnacles (normally filter-feeding crustaceans) grow INSIDE deep water sharks. Some pretty hardcore piercings...

This is interesting. I don’t have a grad lab myself, but if I did I would probably work towards having something like this. No hidden rules, upfront info about things like authorship and data management.

It's NSF CAREER season! I've been fortunate to review dozens of CAREER grants and received one in 2022. Here are the most common mistakes I see and actionable tips to strengthen your proposal.

There’s something infuriating and saddening when someone gets formally heralded as being a great academic researcher and mentor…when, really, that person has spent a considerable amount of their careers being a complete shit and ruining people’s lives 🙁
