After obtaining a joint PhD
in Brain & Cognitive
Sciences and Computer
Science with Dana Ballard
and Mary
Hayhoe at the Center for Visual Science at
the University of Rochester
in 2008, I started
a postdoc at the Frankfurt
Institute for Advanced Studies working with Jochen
Triesch in the theoretical
neuroscience group. Since 2009 I am a lecturer at the Goethe University,
Frankfurt and since 2010 the principal investigator of the 'beliefs,
representations, and actions group'. After a year as a substitute
professor in the Institute
of Cognitive Science
at the University
Osnabrück I am now an associate professor in the department of
psychology at the Technical
University Darmstadt. If you are looking for some of my other activities, please follow this link. |
