The goal of our research is to understand on a molecular level a broad range of macroscopic properties of polymers. Owing to the tremendous diversity of their physical properties, polymeric materials find applications ranging from the most common to the most exotic products in the forms of fibers, plastics, elastomers, adhesives, and coatings. Inevitably, the final properties of the material depend not only on the chemical constitution of the polymer, but also on its physical structure. In our group we explore general aspects of the latter, relating the macromolecular structure and dynamics to the macroscopic properties. 

Present projects in the lab are divided into three sections:
(1) Polymer Physics
(2) Polymer Chemistry
(3) Eye Disease Treatments
