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 will visit Princeton University for one year, during which time his research will focus on computational modelling of neural gain and working memory.
