About me

I am a lecturer in Mathematics, housed with the Living Systems Institute. I work primarily in the College of Engineering, Mathematics and Physical Sciences, but work closely with the University of Exeter Medical School and the College of Life and Environmental Sciecnes. In my research, I apply techniques from mathematical modelling (dynamical systems theory, bifurcation analysis) to understand how networks of cells come together to form biological networks that can perform functional tasks. I am particularly interested in spatio-temporal patterns of neural activity in the brain and their role in memory and spatial navigation, and the synchronisation of electrical activity amongst the insulin-secreting beta cells in the pancreas.

Research Themes - Biology and Healthcare

1) Dementia

My current projects address the formation of oscillatory neural rhythms in two structures of the brain known as the hippocampus and the entorhinal cortex. The cells in these structures are crucial for spatial navigation and memory. Defects in the oscillatory rhythms in these areas can be correlated with memory deficits and loss of spatial awareness. Such deficits are seen prominently in various forms of dementia. By understanding how molecular alterations associated with dementias impact upon network rhythms, we aim to uncover specific pharmacological targets to improve treatment for Alzheimers' Disease.

2) Diabetes

My research into diabetes addresses how alterations in intercellular communication between beta cells in the islets of Langerhans impact their ability to secrete sufficient insulin to regulate blood glucose levels. This research aims to provide new avenues to explore in treatment for type 2 diabetes by understanding how to compensate for the loss of function in beta cell networks. As a by product of this research, I am investigating how mathematical models of beta cells have evolved over the past 4 decades, in particular, as new modelling components and biological processes have been incorporated.

3) Pattern formation in zebrafish

The zebrafish has emerged as one of the key animal models for understanding development in verterbrate species. In my research, I focus on how the fore-, mid- and hind-brain of the zebrafish form during gastrulation; a process involving the establishment of a morphogenetic gradient across what will become the fish's neural plate. In contrast to the classical Turing mechanism of pattern formation, the morphogen signal in zebrafish appears to be transported by long, finger-like projections that facilitate direct cell-to-cell communication. Using a variety of agent-based and PDE models, I aim to uncover under what conditions this transport mechanisms leads to successful pattern formation, and under what conditions it fails.

4) Coarse-grained bifurcation analysis

Almost every question one could ask in biology addresses how phenomena at one temporal or spatial scale affect those at another. Linking these often disparate scales provides a difficult mathematical challenge. One potential way to overcome this hurdle is to use our knowledge of dynamics at fine scales to form approximations of behaviours at coarser scales. Once these equations are formed, we then analyse the coarse-grained system using traditional mathematical techniques. Through this process, we then learn about how small-scale perturbations give rise to distinct behaviour at the coarse scale.

5) Phase-oscillators

Oscillations are ubiquitous in biology. We can observe them on vastly different scales, from those on the order of milliseconds in neurons to those on the order of months and years in diseases such as diabetes. A crucial part of the genesis of rhythms is biology in the synchronisation of activity within networks involving many cells. One way we can attempt to understand the origins of synchrony in such networks, which often arises in the absence of any coordinating group of cells, is to treat the cells as clocks whose natural frequency can be perturbed by other cells in the network. By understanding how biological networks establish robust rhythms, we can hope to find ways to intervene when these important rhythms are disrupted.


I am genereously supported by an EPSRC New Horizons Grant (with Dr Joël Tabak) and am a co-investigator on the EPSRC Hub for Quantitative Modelling in Healthcare.

I have previously been supported by the Medical Reseach Council as a Skills Development Fellow and via a Royal Society Newton Mobility Grant to support a collaborative project with Dr. Marco Herrera and Prof. Hiriart (UNAM, Mexico) to study the interaction of stress hormones and metabolism.

I am happy to support applications for summer internships for undergraduate students to the Society for Endocrinology, British Society for Neuroendocrinology and the London Mathematical Society. I have previously supervised three such internships in the past.

Prospective PhD students

Please get in touch if you wish to discuss developing a research proposal for PhD study. I am open to any project that invovles dynamical systems and biology, particularly if it involves diabetes, neuroscience or pattern formation.
