RESEARCH OVERVIEW

My work as a scientist has been extremely interdisciplinary and strongly collaborative: in my work on granular physics, I drew heavily on the literature of civil and chemical engineering. More recently, I've used the methods of theoretical physics to work on problems in neuroscience (long- and short-term memory), biology (the role of gap junctions in the onset of diabetes, and stochasticity in the visual system of the fruitfly) and computer science (the use of landscapes in optimisation problems).
