Welcome to our site!
Our studies the effect of size, geometry, and interface interactions on the thermodynamics and optical properties of nanostructured materials. Understanding how interfaces and nanostructures affect material properties is crucial in many technological applications where soft materials are constrained at nanoscales, such as coatings, organic electronics, packaged biopolymers, and molecular catalysts. Understanding the physics at the nanoscale enables the design of novel materials, such as stable vapor-deposited glasses or flame-resistant polymer composites or allows us to harvest light for various energy applications. In biological systems, most reactions and transport occur in the proximity of surfaces and interfaces. As such, understanding the interfacial effects become critical in predicting biological function in vivo and in vitro. We focus our efforts on understanding the thermodynamics of these systems on a fundamental with an eye on applications when novel materials properties are discovered. We develop new experimental methodologies that can be readily employed for the characterization of nanostructures in industrial settings. Get a quick tour of our lab and meet our group here!
