    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.
