* Decoupling geographical constraints from human mobility *

🌍🚶 How much of our movement is about human choice and how much is constrained by geography and the spatial layout of locations?

Our paper (out in Nature Human Behavior) gives you a practical way to tell:

I've gotten some new followers so I thought I'd introduce myself.

I’m a 5th-year PhD candidate in network science with an applied math background, working with @barabasi.bsky.social. I study complex systems and love being the "math guy" on interdisciplinary problems. Check out my site or say hi!

The PACER hack is getting worse and worse: "investigators suspect that Russian hackers played a role […] and have grown bolder about how much data they steal over time. That includes pilfering source code […] and vacuuming up sealed case data." www.politico.com/news/2025/08...
Hack of federal court filing system exploited security flaws known since 2020
The intrusion into the federal judiciary’s case filing system was like “taking candy from a baby,” said one person with knowledge of the hack.

New paper is out!🚨 We present a new method to sample random hypergraphs. For many datasets, we show that we can identify based on the hypergraph degrees whether our method will be (much) faster⚡ than standard Markov Chain Monte Carlo methods shorturl.at/tEzBF

OMFG.

One of the surveys being cut by DOGE is the BJS’s Survey of Inmates in Jails.

Jails are simultaneously HUGELY important and preposterously UNDER-STUDIED.

And this will just make it so so SO much harder to study them.

Arguably, jails are more consequential than prisons:

Conducted periodically, the survey provides information on individual characteristics of jail inmates, current offenses and detention status, characteristics of victims, criminal histories, family bac...

Such a gift to have Rick come by @nunetsi.bsky.social this week! Got the whole building jazzed about (multi-scale) network neuroscience.

Enjoyed this discussion with @drmichaellevin.bsky.social

We discussed scientific explanation, its types, causation, reduction/emergence, & other topics.

Great to see the strength of bringing both science and philosophy to the table for hard topics.
