Curriculum Vitae

Throughout his studies Robert Porzel earned degrees in general linguistics, computational linguistics and computer science. Previous to his current work he worked in the interdisciplinary collaborative research center "Language and Situation" (SFB 245) and the special research program "Language Production" (SPP 1022) funded by the German Research Foundation (DFG). Thereafter, he worked at the European Media Laboratory (EML) on several natural language processing projects, i.e. DeepMap, Embassi, SmartKom and SmartWeb, which were funded by the Klaus Tschira Foundation (KTS) and the German Ministry for Education and Research (BmBF). In between he was a guest researcher at the University of California, Berkeley working on a formalization of embodied construction grammar in the EDU project. After moving to the University of Bremen, Robert Porzel started work on contextual computing for autonomous collaborative systems in the DFG-funded special research program "Autonmous Logistic Processes" (SFB 637). He initiated and chaired the biannual ScaNaLU workshop series on scalable natural language understanding systems (2002, 2004 and 2006) and was a member of the steering board of the Interdisciplinary College (IK) - an international spring school on cognitive science, neurosciences and AI - which he chaired in 2010 together with Natalie Sebanz and Manfred Spitzer. His current position is that of "Reader in Digital Media" at the University of Bremen.
