Biography and Research Interests:

Jochen Haller studied Technical Mathematics with electrical engineering as a minor at the University of Karlsruhe. Having finished the studies in 2001, he started working on topics of mobile application security for SAP research in Karlsruhe. The work was conducted in the EU funded FP5 project "WiTness''. Afterwards, his reasearch focus shifted towards security for business processes, especially considering so-called "soft'' security like trust and reputation management. Jochen Haller researched those topics within the integrated FP6 project "TrustCom". Until April 2009, he pursued a PhD thesid as an external PhD student at the Institute of Information Systems and Management. His PhD topic aims at integrating a stochastic trust management approach into a reputation system for Virtual Organisations. This approach roots trust in measurable and observable indicators, inherently characterising an organisation. Furtheron, Bayes and Decision Networks aggregate trust measures towards reputation.

The PhD studies, by now successfully finished, culminated in design, prototypical implementation and multi-agent simulation based evaluation of the STORE (STOchastic REputation) system.
