Ringo Baumann

I am a postdoctoral researcher (Akademischer Rat) in the group [->] of Gerhard Brewka [->]. I'm further associated with the Onto-Med Research Group [->] led by Heinrich Herre [->]. From 2002 to 2009 I studied mathematics, logic and philosphy of science as well as economics at Leipzig University (Germany) and the Universidad Nacional Mayor de San Marcos in Lima (Peru). I received my PhD (Dr. rer. nat.) [->] in 2014 and my habilitation degree (Dr. rer. nat. habil.) [->] in 2019. From Oktober 2018 to April 2019, I was a visiting research fellow at King's College in London (UK) collaborating with Dov Gabbay [->]. Since November 2019 I'm a principal investigator (->) in the Center for Scalable Data Analytics and Artificial Intelligence [->].
My main research interests are formal argumentation, formal ontology and logic-based knowledge representation and reasoning, with a special focus on non-monotonic reasoning.
