Research Interests

As a MRC Research Fellow I work at the interface of biostatistics and informatics in the CHICAS group at Lancaster Medical School. My fellowship research revolves around using routinely collected NHS patient data (from the population of Salford, UK) to investigate the health landscape of a population in both space and time. My work also involves developing statistical models and software for real-time surveillance of routinely recorded diseases in the veterinary sector. I have developed statistical models and software for estimating disease risk of a population, tracked by GPS, travelling through a geographical region.

I have spent several years researching in the Mathematical Physics Group where, notably in 2013, I developed a covariant electrodynamic constitutive field theory for hysteresis (both ferromagnetic and ferroelectric) materials which directly couples to Maxwell’s equations; to our knowledge this was a previously unsolved problem. The hysteretic material may be either stationary or moving (up to around the speed of light). Furthermore I have worked on ways to extend standard models for stationary media (dispersive materials) to models of media in motion (relativistic and non-relativistic). For situations where analytical solutions are unobtainable I have successfully developed numerical algorithms e.g. to simulate the evolution of electromagnetic fields in the presence of a hysteretic material in three dimensional space.

For a short period I also undertook research in the Nonlinear Biomedical Physics Group which included creating mathematical models to simulate macroscopic human brain dynamics. The models were compared to electroencephalographic (EEG) signals from surgical patients. Biological systems are intriguing as they present highly challenging nonlinear open regimes with a spectacular ability to form patterns.
