Siobhán Harty

Postdoctoral Fellow

Headshot_SiobhanSiobhán holds a BA and PhD in Psychology, and a Higher Diploma in Statistics, from Trinity College Dublin. She completed two years postdoctoral training in the Department of Experimental Psychology, University of Oxford, before returning to Trinity to work in the Gillan Lab.

Siobhán’s research to date has primarily focussed on establishing the neural basis of cognitive 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 included neuropsychological testing, behavioural testing, computational modelling, electroencephalography, and transcranial electrical stimulation.

In Claire’s group, Siobhán is leading a large-scale MQ-funded project aimed at developing an algorithmic tool to help clinicians make more personalised treatment decisions for mental health patients – using web-based data collection, cognitive tests, computational modelling, and machine learning.
