Specialist in Distributed Secure Systems

Currently

I’m currently working as Snr. IT Security Engineer at BEWATEC ConnectedCare and contribute significantly to the IT security of the ConnectedCare platform. I am the contact person for all IT security issues and bring security & data protection into the company and to the patients.

Before

I was involved as IT Security Analyst at Verimi in the areas of security, risk & workflow analysis as well as technology & architecture security (e.g. vulnerability scans, coordination of pentests). Before my position at Verimi I was, worked as researcher at the INSA de Lyon in applied research projects with international industrial partners. My work focused on research & development activities (particularly the architectural design & development of a distributed infrastructures, data traceability, security and reputation) as well as fostering relations with international IT partners.

I was developing a blockchain based data processing platform for data traceability (particularly big data und machine learning models), data anonymization & privacy-preserving analytics in a project with a big industrial partner. For the realization I used only modern & free technologies, some of them are Java / Maven / Gitlab (+ CI) / Spring (Boot, Data etc.) / Apache Cassandra / Apache Kafka / Swagger REST) / Angular2 / TypeScript etc. The R&D activity comprised the whole software development lifecycle starting from research, vision, specification, software development up to the deployment with modern technologies such as Docker / Kubernetes / AWS etc.

In Science

Previously, I gained several experiences as researcher and IT specialist at the Dietary Exposure Assessment (DEX) group of the International Research Agency for Research on Cancer (IARC), an institute of the WHO in Lyon, France, as well as postdoctoral researcher at the INSA de Lyon where I was implied in several European projects (e.g. Nathcare, Sphera).

The PhD thesis was conducted in a bi-national supervision (cotutelle de thèse) at the University of Passau (Prof. Kosch) and INSA de Lyon (Prof. Brunie) within the MDPS doctoral college, which evolved to the International Research and Innovation Center in Intelligent Digital Systems (IRIXYS). During the PhD, I adopted a game theoretic approach to communication systems in order to ensure a secure collaborative operation of complex distributed system. In more detail it enables the analysis of the strategic choices of rational selfish individuals. During the PhD in the French-German doctoral college I got the wonderful possibility to combine my scientific curiosity and interest in other cultures and languages.
