Aaron joined the lab as a student research assistant in October 2019. He is a psychology student at Humboldt-Universität zu Berlin and is generally quite interested in perception and passionate about jazz.


Lea KrätzigStudent assistant
Lea is part of the lab since October 2019, after having worked on dementia at Charité Berlin. She studying Psychology at Humboldt-Universität zu Berlin and is currently preparing her bachelor’s thesis, as well as her ERASMUS studies abroad.



Carlos CassanelloPostdoctoral researcher
Carlos has been around the globe before he joined our lab. He’s a physicist, physiologist, and currently most passionate about psychophysics. He joined the lab in March 2013 to work on saccadic plasticity, and perception across large-scale gaze shifts.


Alexander L. WhitePostdoctoral researcher
Alex had just completed his PhD in Cognition & Perception at New York University when he joined the lab in January 2014. He stayed for 1 year and studied the links between perception, attention and eye movements with psychophysics and EEG. We dearly miss him, but fortunately we keep collaborating.

Zampeta KalogeropoulouPhD student
Betty received her Master in Brain and Mind Sciences from the University of Crete (Greece) and a Bachelor in Physics from the same university. She joined us in March 2013 and worked on the mechanisms of feature-based attention. Nowadays, she works in the Mobile Computing Activity Lab at the FORTH-ICS in Greece.

Frederik GewekePhD student (lab rotation)
Being interested in presaccadic attention shifts and visual attention in general, Frederik joined the lab in April 2018. Before coming to Berlin, he studied and worked in San Diego, Dresden and Göttingen. He started out setting up our EEG system, received a fellowship from the Einstein Center for Neurosciences, but then decided to move on and leave academia.

Julius KrumbiegelStudent assistant
Julius got his Bachelor’s degree in psychology at Georg-August-Universität Göttingen, where he wrote his thesis about microsaccades and visual working memory at the German Primate Center. His research interest lies at the intersection of visual perception and technology, which he explored during two research internships in Silicon Valley. He is currently enrolled in the Berlin School of Mind & Brain’s Master’s program.

Hannah WnendtStudent assistant
Passionate about human visual perception and social cognition, Hannah joined the lab in May 2018. After finishing her Bachelor’s degree in Psychology, she started a Master’s program in Developmental Psychology at Maastricht University. In her current project, she studies the impact of gaze and autistic traits on automatic imitation.
