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 metadata to fulldata descriptions. I
also work on constructing mathematical models of biological
systems, parameter inference and optimisation algorithms.
