Ahmet Altınok
Ahmet received his PhD in 2024 on a thesis comprising four studies on the potential effects of the consumption of cocoa flavanols, caffeine, and GABA on cognition. His work focused on attention, working memory, and cognitive control in particular. Accordingly, he employed a range of experimental paradigms to assess task performance, including rapid serial visual presentation, visual search, delayed recall, Flanker, Simon, and Go/No-go tasks. Originally trained as a counselling psychologist, Ahmet has now acquired a taste for experimental work, and aims to continue his scientific career back in Turkey.
Gülşen Balta
Gülşen earned her PhD in 2024. Her PhD project was focused on adaptive event- and object-based perceptual representation. More specifically, she investigated top-down control of temporal integration and working memory consolidation, as a function of both momentary stimulus properties and learned perceptual regularities. Gülşen is now continuing her scientific career in Turkey.
Yining “Ivory” Chen
Yining finished her PhD in 2024, for which she studied visual selective attention, and the effects of memory-driven salience on behavioral performance, pupil dilation, and EEG, in the context of concealed information testing. Her project was co-supervised by Sebastiaan Mathȏt. Yining has now continued her scientific career at the Basque Center on Cognition, Brain and Language.
Joost de Jong
Joost earned his PhD degree Cum Laude in 2024. Under the co-supervision of Hedderik van Rijn, his research focused on the perception of time and the adaptive advantage this affords for working memory processes. Joost has now joined the Integrative Neuroscience & Cognition Center in Paris as a postdoctoral researcher.
Güven Kandemir
As a PhD student in my lab, Güven has focused on the neural correlates of representation in working memory. He has investigated imagery, learning, as well as various other aspects of working memory with both multivariate EEG analysis and behavioral measures. Güven earned his PhD in 2024 and has now continued his career in science, joining the group of Chris Olivers at the VU Amsterdam.
Aytaç Karabay
Aytaç completed his PhD in 2020, and has since continued in my group as a postdoctoral researcher on the ORA project. In his PhD, he used behavioral tasks, such as rapid serial visual presentation and visual search, to study how task performance is affected by stimulus features, and how physiological effects due to the consumption of cocoa flavanols may alter perception and performance in these tasks. Later, as a postdoc, he took up multivariate pattern analysis to study working memory and attention. Aytaç has now joined Daryl Fougnie’s lab at New York University Abu Dhabi. More details can be found on his personal website.
Robbert van der Mijn
During his stay in my lab, Robbert was a postdoctoral researcher on a project funded by Politie en Wetenschap, in which he developed methods and analysis tools to use EEG, pupillometry and rapid serial visual presentation in concealed information tests. Robbert is now employed as a scientist at TNO.
Jefta Saija
Jefta obtained his PhD in 2019. In his PhD project, Jefta investigated links between the auditory and visual modalities, focusing specifically on temporal integration and phonemic restoration. His project was co-supervised by Deniz Başkent and Tjeerd Andringa. Jefta now pursues a career outside academia.
Michael Wolff
Michael completed his PhD Cum Laude in 2021. Working in close collaboration with Mark Stokes in Oxford, his research focused on the neurophysiological mechanisms of the encoding, maintenance and retrieval of behaviorally relevant information in working memory, and the role of attention in these processes. He utilized primarily electroencephalography and multivariate pattern analysis to explore the fast dynamics of working memory specific neural activity. Michael was a postdoc in Mark’s lab on our joint Open Research Area project, and has since joined Rosanne Rademaker’s lab at the Ernst Strüngmann Institute in Frankfurt.
