About me

I'm a research assistant at the department of Business Information Systems (BIS) and the Institute for Applied Informatics (InfAI) e.V.. Since June 2013, I am also working at the computer centre of the University of Leipzig.
I studied computer science with focus on theoretical computer science and the minor subject business administration at the University of Leipzig.
In September 2009 I finished my studies with the masters degree (Diplom-Informatiker) in computer science.
From March till September 2006 I completed an internship at the Institute for Medical Informatics, Statistics and Epidemiology (IMISE) in the research group Ontologies in Medicine and Life Sciences (Onto-Med).
My field of activity was the investigation of logic-based representation formalisms and so I came in contact with Common Logic (CL).
In my diploma thesis Common Logic is a main part too. Thereby the results of my internship were included and extended.
Furthermore the Resource Description Framework (RDF), the Resource Description Framework Schema (RDFS) and the Extended RDF (ERDF) are examined and their relations to Common Logic are considered.

Research interests

• Simulation models for the e-commerce domain
• Simulation techniques especially agent-based simulation, system dynamics simulation and discrete event simulation
• Highly configurable simulation models
• Integration of simulation models
