Our research is highly multidisciplinary. Some of the work benefits strongly from the many robust collaborations that we have with research leaders in science and engineering, worldwide. The below lists the principal investigators with whom we have co-authored papers in 2004, 2005 and 2006. The most active collaborations appear first.
