Research

My research focuses on characterizing, identifying and explaining large-scale patterns found in the structure and function of complex network systems — representing diverse phenomena with physical, biological, technological, or social origins — using principled approaches from statistical physics, nonlinear dynamics and Bayesian inference.

(If you are interested in inferring modular structures in networks using graph-tool, take a look at this HOWTO.)

Open positions

A fully-funded PhD position is available on a project entitled “Inferring the evolutionary forces shaping the structure and function of complex network systems”. This projects involves employing statistical physics, Bayesian inference, machine learning and network theory to model the large-scale structure and function of network systems. The deadline for application is November 30th, 2017. See the project description for more details and how to apply. Feel free to contact me about the project.

Interested PhD candidates are also encouraged to apply for a 4-year studentship through the EPSRC Centre for Doctoral Training in Statistical Applied Mathematics (SAMBa).
