I am a Lecturer in Mathematical Biology at the University of Exeter doing research in mathematical and computational neuroscience. My research interests include dynamical systems, bifurcation theory, modelling of sensory cortex (auditory and visual), perceptual bistability and experiments in auditory perception (psychoacoustics).

Current students
Farzaneh Darki, PhD student working on "Neural dynamics of perceptual competition"
Curtis Alcock, Masters by Research student working on "Can Shannon Entropy be used to measure mishearing and isolate the impact of reduced audibility from the underlying hearing loss?"

EPSRC funded Postdoctoral Research Fellow in Computational and Mathematical Neuroscience
The project will involve developing mathematical and computational models to deepen our understanding of auditory stream segregation. This is a fundamental process in the auditory system that allows us to separate out and focus on distinct sound streams (e.g. voices) in a dynamic noisy environment. This process involves competition in order to resolve different interpretations of a given environment (e.g. different groupings of objects). Many aspects of this process are still not well understood, such as where in the brain segregation of streams is achieved, how the streams are encoded and the driving neural mechanisms. This project will develop a biologically motivated model inspired by a broad cross section of modelling and experimental literature (from anatomical, neurophysiological, brain imaging and behavioural experiments). The models developed will be based on networks of coupled neural oscillators. Neural oscillations are understood to be vital for the encoding of temporal information in auditory streaming. Dynamical systems theory including bifurcation analysis and numerical methods will provide the necessary tools to understand the dynamics of the models developed.
