I am a Professor of Computer Science at Brandeis University with a joint appointment in the Volen Center for Complex Systems.  My research is interdisciplinary with a strong computational basis.  Early in my career my primary focus was in AI and cognitive modeling, but since then I have worked in other areas with different methods. 

Currently my research group is doing research on engineering online collaborative Learning environment. I have also started a project on training and skill acquisition.  The research framework of my lab uses a mix of methods from different fields.  I am a long time member of the Cognitive Science community, which is my core community. The common theoretical themes of my research are planning and activity, intersubjectivity, and communication.
