Current and former lab members @ VSS 2017, left to right: Andrea, Rosanne, Jasper, Janneke, Andrey, Peter, Ilona, Ruben, Laura and Juraj

Janneke Jehee

The lab is headed by Dr. Janneke Jehee. Janneke is a PI (Principal Investigator) at the Donders Institute. Before joining Donders, she worked as a postdoc in the United States (Vanderbilt University & Center for Visual Science, University of Rochester). She received her PhD from Amsterdam University. Here is her CV.

Ilona Bloem


Ilona is a postdoc. She splits her time between our lab and the Spinoza Centre in Amsterdam, where she works with Serge Dumoulin. She received her PhD from Boston University, working with Sam Ling, and did postdoctoral research at New York University, with Jonathan Winawer and Mike Landy. Ilona’s research in the lab focuses on the representation of spatial information in visual cortex, and she is particularly interested in how attention interacts with the precision of these representations. 

James Cooke

James is a postdoc in the lab. He received his PhD in 2019 from Radboud University Nijmegen, working with Pieter Medendorp on Bayesian models of perceptual behavior. In line with his previous work, James’s current research focuses on uncertainty, particularly its representation in the brain and the influence it has on behavior. His other research interests include machine learning, motor control in humans and robots, and adaptive approaches to experiment design. Outside of the lab he enjoys bouldering, reading, and cooking.

Yuxuan Dai


Yuxuan is a PhD student in the lab. She did her master’s in Cognitive Neuroscience with Peter Kok at University College London before joining the lab. Her current research focuses on the representation of uncertainty in cortex. Outside the lab, Yuxuan is a hardcore Sci-Fi fan who also enjoys traveling.

Leni Wei


Leni is an MSc student in the lab, currently enrolled in the Cognitive Neuroscience program at Donders in the Perception, Action, and Decision-Making track. Prior to this, she completed a joint bachelor's program in Psychology at Southwest University and the Australian National University. Leni is interested in computational modeling and probabilistic representations of uncertainty. Outside the lab, Leni enjoys traveling and cooking.
