Research Associate, October 2017 – Present

At the MRC Cognition and Brain Sciences Unit, I work with Duncan Astle to investigate resilience in children. Specifically, our team is trying to figure out what cognitive, character, and brain factors make some children flourish despite adversity. We collect data using iPad tests and neuroimaging (MEG and MRI), and leverage ‘Big Data’ and machine learning in an attempt to make sense of it.

Early Stage Research Fellow, July 2014 – October 2017

As a PhD student at the Cognitive Neurology lab of Masud Husain, I was funded through a Marie Curie grant provided by the European Commission, titled Individualised Diagnostics and Rehabilitation for Attentional Disorders (INDIREA). My research focussed on (in)attention and working memory, specifically on the fundamental mechanism by which we form short-term memories, and on finding potential neuropharmacological treatments of inattention.

The European Commission would like you to know that, although they funded me, all of the views expressed in my work are my own: They do not necessarily reflect the views of the European Commission. While we’re on the subject, I would also like to stress that the views expressed by the European Commission are their own, and do not necessarily reflect my views.

Research Assistant, September 2011 – July 2014

In Utrecht, as a Research Assistant, I helped running research projects (collecting data, programming experiments, and developing data analysis software). Most of the projects concerned eye movements and psychophysics, and are slowly starting to make their way to publication.

As a Teaching Assistant, I helped with five BSc modules and two MSc modules. I taught practicals, developed course materials, and gave a well-received lecture to about 350 Psychology undergraduates.

Publications

My publications are listed below. Under Other output, you can find my software and course materials. If you spot anything that could be useful, please don’t hesitate to contact me, so I can send you a copy.

Articles

pre-prints

A pre-print is a preliminary but public version of a paper. Usually they are currently (very close to) undergoing peer review. I do not list pre-prints of which an open-access and peer-reviewed version has been published.
