I received my PhD from the Technische Universität Dresden in the Software Technology Group for my work in the field of knowledge visualization.
Besides knowledge graphs, semantic technologies, graphics and visualization, my interests include open data and open science. My work at the Saxon State and University Library Dresden (SLUB) embraced fields such as data integration, and graph databases, as well as research data management and building up the Service Center Research Data of TU Dresden. While I'm also interested in new technologies as such, I first of all see them as a promising tool to help solve today's problems, such as information overload, lost trust in facts, and the resulting environmental and social challenges.

My interest in scientific facts and knowledge includes the domain of physiotherapy and I'm looking for partners from this field. Please contact me!

Currently, I'm working as a freelance software developer. See if my standing experience in knowledge engineering, web technologies or visualisation matches your needs. I'm interested to hear about your projects, offering reduced fees for not-for-profit companies, social and ecological untertakings and start-ups.

Skills and Interests

Size mapped to:

Knowledge and Visualisation

In the context of my PhD thesis I started work on the following three projects:

VISO – the Visualisation Ontology

RVL – an RDF(S)/OWL Visualisation Language

A Demonstrator for RVL and VISO

... with an online editor and example collection.

You can find more about my work in the field of knowledge and visualisation in the SemVis Blog.
The blog was initially created as as place for presenting thoughts and ideas around my PhD project. It is now continued as a general means of discussing and publishing things around visualisation of semantically rich or linked open data.


RVL Demo

You can experiment with the RVL and VISO in this online editor. It also provides you with a list of example visualisations and test cases.
