Research

My primary research interest is developing mathematical methods for the tractable representation of complex data systems. My work touches on network science, data science, complex systems and mathematical biology. In particular, I am interested in directed networks, network inference, dynamics on/of networks, temporal networks, and going from meta-data to full-data descriptions. I also work on constructing mathematical models of biological systems, parameter inference and optimisation algorithms.
