Iris received her PhD from the Graduate School of Systemic Neurosciences, LMU Munich in 2013 under supervision of Hermann Müller and Kathrin Finke. Her thesis about adult age differences in visual attention was awarded with the dissertation price 2013 of the German Neuropsychological association. Afterwards, she received funding from the Danish Council of Independent to conduct her independent postdoc project, 2014 — 2016, on arousal, attention capacity and aging in Claus Bundesen's lab at the University of Copenhagen. Since 2016, she is a fellow of the Max Planck UCL Centre for Computational Psychiatry and Ageing Research in Berlin. As a Marie Sklodowska-Curie Research Fellow, she investigates age-related changes in hybrid visual and memory and foraging search tasks together with Jeremy Wolfe at Harvard University. For the period of the ZiF research group, Iris substitutes Werner Schneider's chair at Bielefeld University.
Current Main Research Interests
Iris main research interest is how visual cognition changes in aging. Her current research focuses on adult age difference in "extended" search tasks. These complex tasks resemble real-world searches and allow measuring age-related changes in various cognitive and strategic components within a single paradigm. Using psychophysics, EEG, and cognitive modeling, Iris investigates how attention, memory, learning and decision-making jointly determine performance variations in younger and older age.
