We are an experimental group with broad interests in soft matter physics, applied mathematics, mechanics, and their application to biologically inspired problems. Our experimental skills, the tools in our labs, and around the OIST campus, allow us to work in the general area that concerns macroscopic, non-relativistic matter and their interactions. Our current interests are in problems related to interfacial fluid dynamics, granular solids, and biomechanics of the human foot.

3. Activities and Findings

Professor Bandi started at OIST in July 2012 with most research members arriving in September 2012. During the past year, the Collective Interactions Unit has been busy setting up the laboratory, procurement of equipment, and have started design and construction of experimental setups. Being a relatively young group, we have no findings to report at the present time.
