Short CV


I am a subject matter expert in Semantics, Knowledge Graphs, and Graph Data Management, currently working as a consultant in large-scale Life Science projects with OSTHUS GmbH. I help organisations solve complex real-world data-centric and data-driven problems in order to realise their full potential by using a combination of Semantic Web, Graph Technologies, and Team leading skills.
