Short CV

Bryant Jongkees studied psychology at Leiden University, with a focus on cognitive neuroscience. He obtained his PhD with the cum laude distinction in 2019 at Leiden University, where his research focused on how neurochemistry modulates cognitive and action control. So far, his work has involved both correlational and experimental approaches, including (1) eye blink rates as predictor of individual differences in dopamine activity, (2) L-tyrosine administration as a means of modestly increasing dopamine activity, and (3) non-invasive brain stimulation techniques to modulate cortical excitability, in particular transcranial direct current stimulation and transcutaneous vagus nerve stimulation.

Starting from September 2019, he is visiting Princeton University where his research will focus on computational modelling of cognitive control.


Bryant's research interests primarily relate to cognitive control and goal-directed behavior, i.e., our sophisticated ability to flexibility adapt our goals and behavior. He is particularly interested in the role of neurochemicals such as dopamine and noradrenaline in cognitive control, and is currently focusing on developing computational models of task-switching, a core element of cognitive control.


Bryant coordinates and teaches the research master course Neuromodulation of Cognition, as well as several courses related to applied cognitive psychology at both the bachelor's and master's level.
