Research:

I am mostly engaged in work on graph-based methods for classification, clustering and data analysis. My general research interests are in machine learning, reasoning under uncertainty, databases and artificial intelligence. Other topics of interest to me include social network analysis with its different aspects like discovering communities, relationships, serendipity, trust networks, etc.

Here is a short resume and a list of publications.

Data sets for graph-based classification:

You can find a short description of the data sets here as well as the corresponding Oracle dump files under Wikipedia, DBLP, IMDB.
In case Oracle is not your database, you can download the data in a csv format as well: Wikipedia, DBLP, IMDB.

Personal:

In my free time I conquer walls, rocks, and other non-climbable stuff like empty canvasses, crowded dance floors or charming streets in foreign cities.
