We'll shortly be advertising *four* of our doctoral projects for 2027 entry 🎉📢 (stay tuned 👀)! If you have other projects in applied health and social data science that you'd like me to point people towards, let me know! Happy to help amplify, or even form a small colloquium of resharing 🤝❤️💬.

Feeling deprived of academic talks over the summer? This Thursday I'm presenting new work with @zparolin.bsky.social for the Oxford Metrics & Models seminar. Online talk and all are welcome! 2pm Oxford time, 7am Colorado time. Happy to share the MS Teams link with you. metrics-and-models.github.io

CW: suicide. Honoured to be Guest Editing—with @saurabhkhanna.bsky.social—a Special Issue at ACM-TSC in tribute of my intellectual hero, Aaron Swartz, who died by suicide in 2013 at 26 after extreme prosecutorial overreach. While attempting to expand access to knowledge. CfP: tinyurl.com/4znbk4y2.

Two weeks left until our Call for Papers closes for the 7th International Conference on Social Computing (ICSC'26). Please do submit your papers! Optional conference proceedings, great keynote speakers, nice conference dinner @nuffieldcollege.bsky.social, and more. Details: icsc-conf.github.io!

Today's pushes bring in some speed efficiencies to our new model uncertainty library which make it approximately **14** times faster! Check it out now at robustipy.github.io; accompanying paper getting published very soon, super jazzed 🎷

Delighted to be helping chair ICSC '26 🤖. Hosted: @nuffieldcollege.bsky.social 🏰 When: Sept ’26 🕰️ Details: CfP live 🎉 Optional proceedings, all welcome. More: icsc-conf.github.io. Please consider sharing your work📜! Kindly help us spread the word, and follow @i-c-s-c.bsky.social for updates📣!

The quote of the year came late, but it’s good: “This is LLM generated nonsense. You make a mockery of real research. Do not submit this again.” If the originator of the quote sees this, you will remain entirely anonymous I assure you, but I want you to know that I appreciate you. Happy holidays!

📖👨‍💻🎓 New Courses Alert 🎓👨‍💻📖 The Leverhulme Centre for Demographic Science is launching three upcoming short courses designed for researchers across health, economics, and the social sciences. Led by experts in the field — including @crahal.com — these courses are now open for registration.👇

A pleasure to host @philipncohen.com this week for a fantastic talk on pronatalism & many more engaging discussions about open science, public engagment, and more! #demography @nuffieldcollege.bsky.social @drjenndowd.bsky.social @melindacmills.bsky.social @crahal.com @ridhikashyap.bsky.social

We're holding brief/extremely informal 15 minute meetings with anyone who is interested in either of these positions, scheduled for 19.11.2025 and 17.11.2025, respectively. Email or DM for more information! Please do share details within your network; I think these projects are pretty cool!

A paper of ours just got rejected from a leading computer science journal for being ‘too technical’ and for some disturbing reason the inner economist in me is really proud.

The utility of this data resource cannot be understated. Infinite respect to all of the incredibly talented people who worked on it! 😍

Item Response Warehouse@itemrespwarehouse.bsky.social · 11mo ago

Publication describing the IRW now out! link.springer.com/article/10.3... Over 1000 datasets in there with tools for pulling directly from R!

Big shoutout to Patrick Prag @ppraeg.bsky.social !! Yes I am an editor too, you may thank me, even if you believe my rejection of your paper was dumb and unfair. So, I said it. Back to reading the next shitty paper.

Thanks for asking! Its almost like we made a way to automatically track this on a daily basis, @pietrobiroli.bsky.social 🤩! Kindly see gwasdiversitymonitor.com. See also: Mills, M. C., & Rahal, C. (2020). The GWAS Diversity Monitor tracks diversity by disease in real time. Nature genetics, 52(3).

Did anyone ever update the Scientometric review of GWAS by @melindacmills.bsky.social and @crahal.com , to check if GWAS got more diverse? github.com/crahal/GWASR... www.nature.com/articles/s42...

💡🤖🔥 @keyonv.bsky.social's talk at metrics-and-models.github.io was brilliant, posing epistemic questions about what Artificial Intelligence "understands". Next (two weeks): Alexander Vezhnevets talks about a new multi-actor generative agent based model. As usual, *all welcome* #datascience #css💡🤖🔥

Excited to contribute to this; very exciting stuff by @hggaddy.bsky.social, as usual!

💡🤖🔥The talk by Juan Carlos Perdomo at metrics-and-models.github.io was so thought provoking that the convenors stayed to discuss it in the room afterwards for quite some time! Next, we have @keyonv.bsky.social asking: "What are AI's World Models?". Exciting times over here, all welcome!💡🤖🔥

💡🤖🔥The talk by @klint.bsky.social at metrics-and-models.github.io was truly brilliant. Important work; a clean/intuitive computational design & empirical application from the @itemrespwarehouse.bsky.social! *Next:* Juan Carlos Perdomo on "The relative value of prediction" (v. excited about this)💡🤖🔥

@ramina-sotoudeh.bsky.social gave an AMAZING talk yesterday as part of the #metrics-and-models seminar series👏. Next (30.07), we have @klint.bsky.social on "Reproducing Expert Judgement with Shortened Surveys using Simulated Annealing"🔥! See website for more; metrics-and-models.github.io!

Hurrying to post about RobustiPy, i forgot this fun animation i made for teaching purposes (with @deevybee.bsky.social on the SABS R3 CDT) around when we started developing. Specification uncertainty is just _one_ type of uncertainty, though; our forthcoming work looks at the role of random numbers!

🚀 RobustiPy is out of beta! Feature rich, we hope it becomes useful for model uncertainty / #datascience. We include 🔟 replications, including “unexplained discrepancies” in prior work! 📄 Preprint: arxiv.org/abs/2506.19958 💻 GitHub: github.com/RobustiPy/robustipy 🌐 Homepage: robustipy.github.io

Introducing RobustiPy: An efficient next generation multiversal library with model selection, averaging, resampling, and explainable artificial intelligence

We present RobustiPy, a next generation Python-based framework for model uncertainty quantification and multiverse analysis, released under the GNU GPL v3.0. Through the integration of efficient boots...

“it’s quite heavy on the statistical analysis” is probably one of the nicest inadvertent compliments a politician could ever give to a data scientist. Thank you kindly, @wendychambld.bsky.social!

Maria Petrillo@mariapetrillo.bsky.social · last yr.

Yesterday at the Parliamentary debate on Carer’s Leave MP @wendychambld.bsky.social mentioned our work on the income loss caregivers face as a results of providing unpaid care @dvaldenegro.bsky.social @crahal.com Working paper available here: arxiv.org/abs/2411.10314

One of the world's great books now accompanied by one of the world's great programming languages ♥️. Can't wait to read this.

A new Python edition of "Forecasting: Principles and Practice" is now available online at otexts.com/fpppy/. Thanks to @azulgarza.bsky.social, Cristian Challu, Max Mergenthaler, Kin Olivares & Nixtla for making this happen. #forecasting #python

Just moved to @zed.dev as my go-to text editor. Blazing fast with minimum latency (of any sort), so extremely feature rich, immensely beautiful, and clearly an IDE made by people who know what developers want and need. I absolutely love it; highly recommended!
