My Homepage

I'm an Associate Professor in Applied Mathematics at the University of Adelaide. I study how information moves over social networks using mathematical models, coupled with data science techniques. My research interests are in computational social science, human dynamics, online social networks, as well as data assimilation and the mathematics of weather and climate. Please consult my homepage for further information.
