About me I am a visiting scholar in the Department of Computer Science at Wellesley College. This is my second year at Wellesley. Previous to that, I was at the University of Marburg, where I received a PhD in Computer Science in 2007. Here is my old homepage.
Research My primary research interests are in information retrieval and natural language processing. My latest project is about using sentiment analysis techniques to evaluate the public discourse in online social media forums.
Teaching In Fall 2009, I am co-teaching two classes: CS110 (Computers and the Internet) and CS114 (The Socio-Techno Web). In Fall 2008 I co-taught CS315 (Web Search and Data Mining).
Projects Our CS114 course is participating in a pilot program that will teach non-programmers to program for the Android G1 phones using a new visual programming environment, App Inventor for Android.
