Abstract

The Collective Interactions Unit is broadly interested in the experimental investigation of macroscopic phenomena that arise from collective interactions of individual units or entitites, be they biological, chemical, or physical in origin. We borrow experimental and analytical techniques from several fields, and see them as a means to an end, with the problem guiding us on what tools to deploy. The problems we study arise both in the natural and engineered contexts, and normally fall in one of the following general categories:

  • Commonplace phenomena easily replicated in the lab, but not easily understood because they lie at the intersection of formal disciplines.
  • Phenomena normally associated with a particular system, which through mathematical anology, may be studied in a different context.
Note: Dr. Bandi’s employment as faculty at OIST started on September 1, 2011. He spent the 2011-12 academic year as visiting faculty with the School of Engineering, Brown University because Lab 2 was still under construction. The Collective Interactions Unit will commence formal research operations at OIST starting July 2, 2012.
