Glad our study has been useful for the @BostonGlobe :)
One hundred percent of professors will agree with this: College campuses are being suffocated by administrators bostonglobe.com/2026/09/09/o… via @BostonGlobe

Exciting faculty opening at Northwestern's McCormick School of Engineering, in partnership with Northwestern Innovation Institute. This candidate can be placed in any department within the Engineering school, with initial preference in IEMS or ESAM. It's open-ranked with a preference for senior candidates. I'm chairing the committee with @noshir and Danny Abrams. Please help us spread the word! and please feel free to get in touch if interested!
Between 1985--2023, MIT's faculty grew 9%. Administrative staff grew 189%. 📈 Why? In new @PNASNews paper, we use dynamical system model to show administrative bloat can emerge without empire-building--just from well-intentioned problem-solving gone awry pnas.org/doi/10.1073/pnas.25…

Thanks @mitsloan for covering our recent paper on function diversity across complex systems mitsloan.mit.edu/press/new-s…
Thanks @sfiscience for an accessible coverage of our paper! @hyejin_youn
A mystery novel, a history book, and a fantasy epic may have little in common in plot or style. But count the words inside them and a strange regularity appears: many new words show up early, then fewer and fewer as the author reuses what has already been introduced. That pattern, known as Heaps’ law, turns out not to belong to books alone.
A new study in PNAS, led by SFI and MIT researchers, finds that the same rule also describes how complex systems grow, from living cells and corporations to universities and government agencies. As these systems get bigger, they add new functions more and more slowly. While systems vary in how much they invest in creating new functions, once those exist, their subsequent growth slows, following a remarkably universal pattern known as sublinear growth.

New paper in PNAS: We find Heaps' law, empirical regularity first identified in how diversity of vocabulary scales in books, also describes function diversity in cells and many human organizations (with cities being a notable exception). w/ @sfiscience

Mastering a skill can take decades, but the learning process unfolds across multiple timescales, from mere moments to days. A new paper by three former SFI postdoctoral fellows presents a theoretical model of nested timescales of learning, offering a unified, multi-scale account of skill acquisition.
The study grew from a conversation between co-authors @mingzhen_lu, @VickyCYang, and @TylerMarghetis during SFI's 2020 Postdocs in Complexity conference.

Excited to share our new paper in @Nature_NPJ Complexity! We propose a unified, multiscale model of skill acquisition—linking moments to decades. Ideated at the @sfiscience -@JSMF conference research jam, and years (many revisions) later, it’s finally out. nature.com/articles/s44260-0…
Big thanks to Faye Flam and @Bloomberg for the thoughtful interview and excellent article on polarization. bloomberg.com/opinion/articl…

Thanks SFI for doing a nice re-cap of our paper!
A significant body of research has investigated why, as city populations grow, so do violent crime, contagious diseases — and per-capita GDP. A new paper now finds that cities with strong interconnectivity show a marked economic benefit, even beyond normal scaling.

New paper on urban scaling & global connections. We show global connectivity (through multinational firms), plays a significant role in GDP. After accounting for global connectivity, effect of population is no longer distinguishable from linear.
We hope this motivates rethinking of urban scaling models to integrate global & local effects. Paper (w/ @JakeJJacksonRI & Chris Kempes) at @PNASNexus: academic.oup.com/pnasnexus/a…
