The threshold and quasi-stationary distribution for the SIS model on networks We study the Susceptible-Infectious-Susceptible (SIS) model on arbitrary networks. The well-established pair approximation treats neighboring pairs of nodes exactly while making a mean field approxima...

We found a nice way to accurately solve the SIS model. Rather than expanding in space with ever larger moment closures (pairs, triples, ...), we expand in time. No more difficult than pair-approximations yet much more accurate.

Statistical Laws in Complex Systems This book provides a unifying approach to the study of statistical laws, evaluating their role in the theoretical understanding of complex systems

"Statistical Laws in Complex Systems: Combining Mechanistic Models and Data Analysis", my 150p monograph written at @SydneyMaths and @mpi_pks is now published by @SpringerNature:

A thread:

How individual systems and their connections react to each other to ensure stability of the whole. We live in a complex world with a plethora of connections and interactions. Many important processes, such as power grid dynamics, ecological interactions, opinion formation, or brain plasticity, can ...

Our new article in Chaos. One of my favorite articles so far. Connecting different disciplines and building on recent breakthroughs in ancient fields (Linear Algebra!).

Another great visualization—The Network of the Conclave maps the social structure of the papal conclave, where each node represents a cardinal, colored by doctrinal orientation. Few modern decision-making processes combine secrecy, ritual, and influence as vividly as this one.
