Mathematical biomedicine and survival analysis.
Statistical mechanics of disordered manyparticle systems.
Processes on complex networks and random graphs.
Topics and projects

Medical statistics: Bayesian
analysis of survival data in presence of cohort heterogeneity
and competing risks
 Mathematical immunology:
dynamics and statics of large
immune system networks in the finite connectivity regime

Theory of cellular
signaling processes in e.g. proteomic, gene regulatory, and metabolic networks

Analysis of sparse random graph ensembles

Equilibrium and nonequilibrium
theory of processes on complex finitely connected graphs

Theory of
primary/secondary/tertiary structure generation in heteropolymers
and proteins

Calculation of the stationary
state probability distribution for nondetailed balance spin
systems

Dynamics of econophysical models
such as minority games, describing cooperative phenomena in
markets.
I am involved in
the creation of a multidisciplinary research and teaching
infrastructure at King's College London, to combine and exploit expertise at the
interfaces between biology, medicine, physics, computer science and
mathematics. See the websites of the
Institute for Mathematical and Molecular Biomedicine and the
Systems Biomedicine Graduate Programme. A brief nontechnical introduction to the role of mathematics
in cancer research can be found
here.
