Mission statement

Our research interests lie at the interface between biology and physics at the mesoscopic scale. The objective of my research is to understand and engineer the behavior of complex matter at this length. Toward this goal, our research is rooted on a multidisciplinary team-work with our group members (and collaborators) from Physics, Chemistry, Microbiology, Mathematics and Engineering. Currently we are studying self-organization in two model complex systems - complex fluids and microbial systems, by tracking particles and microbes using advanced optical microscopy techniques. Our research will have applications in broad areas like fabrication of metamaterial/biomaterial, treatment of bacterial infections, biofouling control, sustainable bioenergy and water remediation.
