The Trade-Off between Directness and Coverage in Transport Network Growth Designing spatial networks, such as transport networks, commonly deals with the problem of how to best connect a set of locations through a set of links. In practice, it can be crucial to order the im...

Strength and weakness of disease-induced herd immunity in networks | PNAS When a fraction of a population becomes immune to an infectious disease, the population-wide infection risk decreases nonlinearly due to collective...

New paper in PNAS!🎉 doi.org/10.1073/pnas...

Is herd immunity to infectious diseases effective when induced by natural infection? Earlier studies have suggested that population heterogeneity makes disease-induced herd immunity more effective than previously thought. Our work challenges this notion.

🚨🚨 New preprint just dropped! In collaboration with @colltoaction.bsky.social, Cliff Joslyn, @fralotito.bsky.social, Audun Myers, Joshua Pickard, Brenda Praggastis, and Przemysław Szufel, we define a new data sharing standard for higher-order networks. arxiv.org/abs/2507.11520

Decoupling geographical constraints from human mobility Driven by access to large volumes of movement data, the study of human mobility has grown rapidly over the past decades. The field has shown that human mobility is scale-free, proposed models to gener...

Deterministic simplicial complexes We investigate simplicial complexes deterministically growing from a single vertex. In the first step, a vertex and an edge connecting it to the primordial vertex are added. The resulting simplicial c...

#NetSci2025 in Maastricht was fantastic! I had great chances to present my works at the satellite-Critical Phenomena In Networks (CPIN) and the parallel session-Mobility and spatial networks. I thank to all of my collaborators and mentors for amazing support :)

Looking forward to see your work soon on arXiv!

GitHub - yang3kc/llm_for_css: Guide on how to use LLMs for computational social science research Guide on how to use LLMs for computational social science research - yang3kc/llm_for_css

I'm releasing the v2.0 version of my guide on using LLM (mainly OpenAI models) for computational social science tasks. Major changes:
- Adopt the new Responses API.
- Better handling of the structured output.

Congrats Dr. Kaiser @kaiserdaniel.bsky.social who successfully defended his dissertation 🥳 I’m glad I was part of Daniel’s amazing project and sad that he will leave the group 🥲 Wish you the best at UVA 👏🏻

I've just published a new version of the pygris #Python package, helping you work with U.S. Census Bureau TIGER/Line shapefiles and other data resources.

Grab the new version now with `pip install pygris`; it resolves issues with the Census website and ensures you can get your data.

Paper alert! 🚨 We investigate Bluesky’s journey from an invitation only platform with a few thousands of users to reaching 30 million users in terms of user activity and network growth.

Later, I will archive other papers on advanced concepts in message passing methods and their application to other fields of network science on the repo as well :)

This week, I gave a one-hour tutorial at our group meeting on message passing methods on complex networks and their application to percolation studies. I’m always reminded that the best way to learn is to teach someone else!

We propose a minimum-cost percolation (MCP) framework to model resource consumption in transportation networks, applied to the US air system. Encouraging cooperation among air carriers can boost the system’s robustness to disruptions!
