Jeshua Tromp is a PhD candidate at the Cognitive Psychology Unit under the supervision of Prof. Dr. Sander Nieuwenhuis. Jeshua holds a Bachelor’s degree in Pharmaceutical Sciences and a Master’s degree in Neuroscience & Cognition, both acquired at University Utrecht. For his final Master’s project, Jeshua was a visiting researcher at the Karolinska Institutet (Stockholm), under the supervision of Prof. Dr. Torkel Klingberg. There he focused on the intersection of executive functioning, genetics and the developing brain. Now, complying with his interest in executive functioning and the workings of the brain in general, his PhD project focusses on the impact of arousal on cognitive control. He will be making use of a variety of methods, amongst which multimodal neuroimaging (EEG, fMRI), psychophysiological measurements (pupillometry) and pharmacological interventions.
