Our latest paper, "Structural roles and gender disparities in corruption networks," is out in Scientific Reports. We find that females comprise just 10%/20% of corruption agents in Brazil/Spain, yet network properties of these criminals show no significant gender-specific bias - rdcu.be/ei2l0

Our paper "Two-by-two ordinal patterns in art paintings" has just been accepted in PNAS Nexus. We explore 2x2 ordinal pixel-intensity patterns across ~140k paintings, revealing visual structures that track artistic styles and historical shifts in art. arxiv.org/abs/2503.09844

Our new paper, "Impact of inter-city interactions on disease scaling," is out in Scientific Reports! We explore how population & commuting networks drive infectious disease incidence across Brazilian cities.

Urban Scaling: Allometry in Urban Studies and Spatial Science
Urban allometry empirically describes how “things”, for example crime, GDP, emissions, energy use, area, street length, housing prices, etc. change in cities when their size, in terms of population, i...
