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 received her PhD from Amsterdam University, working with Victor Lamme and Jaap Murre. She worked as a postdoc for two years with Dana Ballard at the University of Rochester, NY, and for another three years with Frank Tong at Vanderbilt University, TN, before joining the Donders Institute in 2010, where she is a PI (Principal Investigator). Here is her CV.

Andrey Chetverikov

Andrey is a postdoc in the lab.†He received his PhD in 2014 from St. Petersburg University, Russia, working with Viktor Allakhverdov. After†that†he worked at the University of Iceland with Ńrni KristjŠnsson in 2015-2017, where he studied the representation of probabilistic perceptual ensembles. Andrey’s research in the lab focuses on visual uncertainty and its representation in the brain, with particular emphasis on uncertainty in motion perception. His other interests include visual statistics, short-term learning in vision, and perceptual conflicts. When not in the lab, he enjoys traveling and reading good fiction.

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.

Laura Geurts

Laura is a PhD student in the lab.†She studied Artificial Intelligence at Radboud University and Neuroscience at the University of GŲttingen, and first joined the lab as an MSc student. Her research focuses on the neural basis of perceptual decision-making under uncertainty using novel data analysis techniques. Outside the lab, she enjoys sports (speed skating in particular) and traveling. †

Joey Zhou

Joey is a PhD student in the lab. Before coming to Nijmegen, she did her MA at New York University with Marisa Carrasco and Larry Maloney. Together with Janneke and Floris (de Lange) at Donders, Joey focuses on modeling priors in perceptual decision making. She is secretly a pianist outside the lab.

Marc Pabst

Marc is an MSc student†in the lab. He is enrolled in the Cognitive Neuroscience program here at Donders, and holds a bachelor’s degree in Psychology from the University of Leipzig. In the lab, Marc studies how uncertainty is represented in computational models to improve our understanding of uncertainty in cortex. Outside of the lab, Marc enjoys running and hiking.
