Trying to understand attention and working memory through computational modelling of behaviour and EEG (and investigating sports on the weekends).

Research Interests

My research focusses on (in)attention: how it works, how it relates to working memory, and how we can treat patients who suffer from attentional disorders.

I am particularly interested in working memory encoding, and use computational models and EEG (electroencephalography) to investigate its dynamics.

Attention is a versatile topic, and my interests are broad. With collaborators, I test neuropharmacological treatments that could improve spatial attention, which I investigate with pupillometry and visual search. In addition, I work on how attention is biased by threatening information, and the role of threat avoidance in anxiety therapy. In my spare time, I investigate temporal attention in racing sports, and how it can bias Olympic competitions.

As a part of my research, I develop software with many different applications. One example is PyGaze, a Python toolbox for quick and easy programming of eye-tracking experiments that supports a broad range of tracker types. Another example is CancellationTools, an application that allows researchers and clinicians to administer computerised cancellation tests, and to analyse their results with the click of a button. It calculates indices of attentional biases, executive functioning, search organisation, and working memory, and it produces helpful data visualisations.

Eye Tracking Demo

This video demonstrates the process of pupil tracking, which is often employed to measure pupil size, but also to infer where someone is looking. The basis of the technique is simple: we try to locate and find a very dark part of the image (in this case indicated by the researcher, who clicks on a pupil in the interface). More elaborate software based on the same principle can be used to test spatial attention (where are you looking at?) and pupil responses (which are thought to reflect certain cognitive and emotional processes).
