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 worked closely in recent projects. The most active collaborations appear first. (We have also worked with many postdocs, graduate students, visiting scientists and others not explicitly listed below.)
