I investigate the social cognitive and neural mechanisms that underlie social functioning in healthy individuals and individuals with schizophrenia. In my research I use neuroimaging and experience sampling methods to study the link between social brain mechanisms and real world social functioning.

After completing my PhD on the cognitive and brain mechanisms of social functioning in schizophrenia at the VU Amsterdam and the Institute of Psychiatry, Psychology and Neuroscience, King's College London in 2012 I worked at both institutes as post-doctoral researcher . In October 2017 I started as lecturer in Psychology at City University.

I contribute to UG teaching in Biological Psychology (PS1005), Cognitive Psychology (PS2003) and Clinical Psychology (PS3018). I am personal tutor and supervise research students on undergraduate and postgraduate level.

Enquiries for PhD and internship positions are welcome.
