I graduated in 2006 with a Ph.D. in Computer Science from LMU Munich, Germany. Since 2007, I am a Postdoc at the Department of Computer Science at Cornell University, as a member of the Database Group lead by Prof. Johannes Gehrke and Prof. Christoph Koch.

In fall 2008, I spent three months working for the enterprise search company FaST, A Microsoft® Subsidiary in Trondheim, Norway.

I am generally interested in the different aspects of data access, including search, data management, data analysis, collaboration and user interfaces. My current research is in web data management, extraction and analysis. In the Cornell Web Lab Project, a joint endeavor with the Internet Archive, we are building applications and a service infrastructure for collaboratively analyzing hundreds of terabytes of web data. Recently, I have started working on large-scale parallel data analysis using the Map-Reduce paradigm. My earlier research was in the area of XML retrieval, with a focus on efficient index structures and caching techniques and intuitive user interfaces. See the complete list of my publications.

I like to do research with concrete applications in mind, and part of the fun is building working systems. As a passionate Java and Web programmer, I enjoy developing software using modern tools and frameworks. For example, I am excited about the Google Web Toolkit and related toolkits. Learning to use new techniques is also an important part of the various student projects that I supervise. For example, for our visual web data extraction tool we have adapted Aspect-Oriented Programming to model the complex user interaction. To learn more about the extraction tool, have a look at the video screen capture and the latest screenshot.

During my academic career, I have had the chance to contribute to the research community both as a peer reviewer and member of program committees. See the list of my professional activities. In my spare time, I enjoy playing and composing piano music and taking photos with my wife Marion. Check out a selection of our photos at
