Building More Resilient Teams: A Mathematical Approach Using Hypergraphs When organizations need to assign people to projects, they face a fundamental challenge: how can they form teams that continue to function if someone becomes sick, leaves the company, or is otherwise ...

Our new paper on searching the space of hypergraphs to solve constrained combinatorial optimization problem is out. This was joint work with Guilherme Ferraz de Arruda, Wan He, Nasimeh Heydaribeni, Tara Javidi, and Yamir Moreno.

How string theory helped solve a mystery of the brain’s architecture Using the same math deployed in string theory, network scientists have solved a standing mystery about the brain’s architecture.

In an interview with Northeastern Global News, #NetSI Csaba Both and @barabasi.bsky.social discuss their 𝘕𝘢𝘵𝘶𝘳𝘦 study on physical networks and whether 1940s minimization principles explain neural growth.

Researchers find Milan nightlife hubs bring rich and poor together Northeastern University research using cellphone data from 100,000 people reveals where different income groups mix socially in Milan.

Take another look at this study on social segregation in Milan, done by @riccardodiclemente.com and colleagues. It shows that diverse amenities, strong transit, and public spaces can turn outer neighborhoods into “social bridges” across income groups.

Artificial intelligence is reshaping jobs not just eliminating them, research shows By framing your job as a set of skills, Northeastern researchers can measure an individual’s “unemployment risk.”

Measuring AI’s impact on work goes beyond job losses, t’s about how tech reshapes skills & tasks. @estebanmoro.bsky.social and collaborators are building the 𝙊𝙗𝙨𝙚𝙧𝙫𝙖𝙩𝙤𝙧𝙮 𝙤𝙛 𝙐𝙎 𝙅𝙤𝙗 𝘿𝙞𝙨𝙧𝙪𝙥𝙩𝙞𝙤𝙣 to track job skills and predict unemployment risk more accurately.
