Siobhán Harty

Postdoctoral Fellow

Headshot_SiobhanSiobhán received her PhD from Trinity College Dublin under the supervision of Redmond O’Connell and Ian Robertson. She completed her first postdoc in the Department of Experimental Psychology, University of Oxford. Siobhán’s research to date has primarily focussed on establishing the neural basis of executive functions and examining interventions to improve these functions in young and older adult populations. She has been particularly interested in understanding why some individuals respond to such interventions and others do not.

Research tools have neuropsychological testing, behavioural testing, computational modelling, electrophysiology, and transcranial electrical stimulation.

In Claire’s group, Siobhán is leading an MQ-funded project aimed at predicting treatment response in clinical samples, using cognitive tests, computational modelling, machine learning and web-based data collection.
