During my PhD and previous postdoc, I have studied whether and how language (mainly words) affects other supposedly nonlinguistic systems such as categorisation and visual processing. I have also worked on how several languages are processed by the brain of bilingual speakers.
 
I am particularly interested in the underlying cognitive processes of what I study. For this purpose I mainly use neurophysiological methods such as EEG and ERPs. In recent months, I have also been particularly interested in relating brain data to behaviour as well as studying individual differences which have too often been overlooked by the scientific community. For this purpose, I like to use linear mixed-effects models in the R environment. With regards to EEG, I am also becoming more and more interested in looking at brain oscillations and what these can tell us about our brain dynamics. I am therefore in the process of learning to implement synchronisation measures such as PLV, and Granger causality on EEG data. Finally, I am also in the process of applying Growth Curve Analysis (implemented through linear mixed-effect modelling) to study ERP data. One of the main motivations behind this endeavour are related to what I consider to be “bad” practices in the evaluation of statistical significance in ERP data, which are often prone to too much influences from experimenters’ choices (e.g. time-window selection). This is work in progress however, and I will greatly value any input at this stage.
 

Here in Leiden, I am part of the AThEME project studying various facets of being multilingual –a great endeavour! Currently, we are planning to study multilingual interaction with a focus on foreign accent processing. We ask questions such as: Is information delivered in a non-native accent processed differently than when it is delivered in a native accent? Do people behave differently on a series of non-linguistic tasks depending on which of their several languages they use to perform the tasks? Many more will come I’m sure! I would also like to bring my interests in language-perception interactions in multilingual speakers.

Primarily, I am hoping to develop a side of my research (language processing) which has been more of a secondary goal in my previous research. I think being able to see both sides of the coin (how do we “do” language and what language does to us) is essential in order to have a more fine grained understanding of what being multilingual really entails. I am also hoping to develop some of my technical skills by implementing brain imaging techniques such as MRI and structural connectivity. I therefore strongly value collaborations between members of the various institutes and will be more than happy to share what I know and learn from others.
