I am a chief research scientist of the Systems and Machine Learning (SysML) group at NEC Labs Heidelberg. From 2012-2015 I was a research associate at the University of Washington in Seattle. I was also a member of the Data and Web Science Research Group at the University of Mannheim.

My research interests include representation learning for graph-structured data, unsupervised and semi-supervised learning, probabilistic graphical models, and statistical relational learning.

I am also co-founder of several open-source digital humanities projects such as the Indiana Philosophy Ontology Project and the Linked Humanities Project.
