Short CV

Frank Breitinger started his scientific career in 2005 at the University of Applied Sciences Mannheim (Germany), where he studied computer science, spent one semester at the University of Maryland (US) and completed his bachelor’s degree in March 2009. While his Bachelor-Degree he gained professional experience at the sobedi GmbH in Mannheim.
Afterwards he changed to the Hochschule Darmstadt (h_da, Germany) because of his interest in IT-Security. While doing his Master, he was self-employed and also worked for the computer science department. He finished his studies in February 2011 with the Masterthesis „Security Aspects of Fuzzy-Hashing“ together with Prof. Dr. Harald Baier and Prof. Dr. Christoph Busch.
After receiving his M.Sc. in 2011, he started his Ph.D. at the Center for Advanced Security Research Darmstadt (CASED, Germany) within the working field approximate matching.
