We are an interdisciplinary research group interested in a broad range of fundamental and applied aspects of materials chemistry in general, and macromolecular science in particular. Our efforts are geared towards the design and synthesis of adaptive polymers and understanding the molecular level events governing their behavior in various environments. Synthetic efforts are directed towards the development of multi-phase stimuli-responsive nano-materials. Parallel efforts focus on the design of self-healing polymeric materials capable of upcycling with light sensitivity, corrosion inhibition, anti-fouling, antimicrobial, and other unique attributes. Using chemical imaging along with an array of other spectroscopic and macroscopic tools, Urban Research Group members design and develop new generations of materials with adaptable, sensing, and signaling  properties.
