I am an applied mathematician developing and analysing mathematical models to address problems arising in the health and social sciences. 

The role of mathematical modelling to explore infectious disease control is well-established and involves a wide range of modelling approaches. My particular interest is to explore the potential for classic techniques such as optimal control and feedback control to contribute to the literature in this field. My goal is to find an approach to control that might be easily translated into practice and that might result in clearly defined outcomes in terms of the levels of infection post control intervention. Most of my work is based on underlying deterministic infectious disease processes although I have also undertaken some work that is based upon stochastic and network models. 

As part of my growing collaboration with colleagues working in countries of sub-Saharan Africa, I have become increasingly interested in using mathematical models in the context of criminal activity and crime control. 

My work on drug monitoring and delivery focuses on drugs that are delivered or monitored across the skin.  The challenge here is to work out how the drug molecules might partition and move through the skin barrier that is highly heterogeneous in nature. Here I work with systems of reaction diffusion advection equations for which parameter estimates can be made using the empirical studies of my collaborators working in the Department of Pharmacy & Pharmacology. The resulting mechanistic models diverge from classical pharmacokinetic (PK) models of drug delivery but are of increasing interest to colleagues working in the Pharmaceutical industries who are aware of the limitations of a purely PK approach. Linked to this activity, I am a member of the UK network for Quantitative Systems Pharmacology.

I have a long-standing interest in Widening Participation in HE. In my own work with students at the university, I am interested in developing effective learning environments to support the diverse needs of students. I also have a strong track record of working at the School-University transition. Currently this involves a collaboration with the AMSP (https://amsp.org.uk) to encourage students from the state school sector to study mathematics post-16 (A level and Core Mathematics).
