About my research interests

My area of research is broadly at the interface between mathematical biology and statistics where I am interested in developing realistic stochastic models alongside Bayesian statistical methodologies that allow us to infer models from observed data. Often the modeling side involves very interesting non-linearities and stochastic processes giving rise to statistical methodologies that are computationally challenging. I am in particular interested in the modelling of oscillatory phenomena in biology (epidemics, gene expression, molecular clocks, etc) combined with the analysis of temporal and/or spatio-temporal data (from single cells to meta-populations) from such systems and have worked on applications in epidemiology (dynamics of infectious diseases), on analytical population dynamics in ecology, and on modelling and inference for the stochastic transcriptional dynamics of single genes and transcriptionally interacting genes (including inference about small networks of genes).

My recent collaborations also include addressing questions in chronobiology and circadian rhythm with collaborators in the biological sciences and medicine. In collaboration with Francis Lévi and members of the Chronotherapy group at Warwick Medical School, Warwick Systems Biology and INSERM France, I am developing statistical methods and models for inference from large data sets of biomarkers on circadian oscillations, such as actigraphy data, with the aim of using these for personalized medicine and treatment of cancer patients in their home, as well as basic research in chronobiology.
