ABSTRACT 

"The Nature of Glass Remains Anything but Clear", as one NY Times article has put it. We use femtosecond optical Kerr effect spectroscopy to study the dynamics of glass-forming liquids, with the aim of identifying the mechanisms which cause different relaxations such as alpha relaxation, fast beta relaxation and "Johari-Goldstein" beta relaxation. Biopharmaceutical drug sales accounted for $80B in 2007. 36% of all protein drugs fail in manufacturing. So far there is no systematic, rational approach for dry protein formulation. By studying the glass dynamics, our ultimate goal is to gain understanding of protein preservation and stabilization.
