Researcher Summary

As a data scientist I explore and try to make sense what happens in complex, dynamical networks. I'm interested in ecological networks and the evolutionary processes that modify them in time; in particular I develop mathematical and statistical tools to study the relationship between ecological biodiversity and evolutionary diversity.

I'm also interested in Social Networks, especially online. I try to understand what makes them work in the way they work.

Subject Area: Disciplines

  • Biology: Ecology, Evolution and Behaviour: Biodiversity/Conservation; Evolution
  • Engineering and Technology: Simulation, Control and Computer Modelling
  • Mathematics: Applied Mathematics; Biomathematics; Computable Mathematics
  • Statistics: Applied Statistics
  • Digital Humanities: Digital Humanities
