Research summary

My research focuses on visuo-motor processes, such as rapidly responding with eye or hand movements to changes in visual signals. My aim is to uncover how the human brain takes these rapid decisions, and for this I rely on sophisticated analysis of behaviour, computational modelling and electrophysiology (EEG, MEG). I apply this research to better understand fluctuations in performance within individuals, as well as individual differences in the healthy population and clinical conditions such Alzheimer’s disease.

Teaching summary

I am coordinating the MSc “Brain Imaging of Perception and Action” module and deliver one year 2 Perception and Action practical. I am also a coordinator of the Placement Scheme and organises the international departmental talk series (Colloquia).

Computational modelling of visuo-motor decisions. My team uses a range of models (linear accumulators, diffusion, neural field models) to offer quantitative approaches to behaviour and explicitly links to brain activity.

Postgraduate research interests

All action decisions are subject to spontaneous fluctuations, resulting in large variability in speed and accuracy across time. My approach focuses on fast visuo-motor decisions and I am specifically interested in the following questions:

What is the balance of stochasticity and determinism in simple decisions, including free-choice?
What is the temporal structure and electrophysiological correlates of endogenous variance?
To what extent future decisions can be predicted from recent behaviour and brain activity?
What are the metacognitive correlates of poor performance?
What underlies hypervariability in attention disorders, hyperactivity or dementia?

If you are interested in applying for a PhD, or for further information regarding my postgraduate research, please contact me directly (contact details available on the 'Overview' page), or submit a formal application.
