Welcome to my personal site.
I am a postdoc in Dr. Douglas Garrett's Lifespan Neural Dynamics Group at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research, located at the Max Planck Institute for Human Development, Berlin, Germany.
I am interested in the brain mechanisms and processes that transform subjective perceptual experiences into purposeful actions – perceptual decision-making, in short. In particular, I like to study how these mechanisms change with age and how the state of arousal affects decisions – for example, how decision-making in drowsy and alert brains differs from each other. I focus on the role of moment-to-moment neural variability in these processes.
I use visual and auditory perceptual tasks to study these topics, often combined with eye tracking and pupil size measurements as well as neuroimaging methods such as electro- and magneto-encephalography (E/MEG), as well as functional magnetic resonance imaging (fMRI).
In my current work I investigate if humans can adapt their decision-making style to environmental demands by strategically biasing their decisions towards choices that best fit the decision context. My work suggests that humans can indeed do this by adjusting the moment-to-moment variability of neural signals, as measured with EEG. Furthermore, in another study I combine eye tracking and fMRI to investigate how people view pictures of everyday scenes and how their viewing style is reflected in the dynamics of their brain activity. Finally, in another line of research I use psychopharmacology and MEG to study how the arousal-related noradrenaline and dopamine brain systems influence neural variability and affect the way in which we make basic perceptual decisions.
