Dr. Bruce A. Garetz is currently Professor and Associate Chair of the Chemical and Biomolecular Engineering Department at the New York University Tandon School of Engineering.  He received his A.B. degree in Chemistry and Physics from Harvard College in 1971 and his Ph.D. degree in Physical Chemistry from the Massachusetts Institute of Technology in 1976.  After serving two years as a postdoctoral fellow at the University of Toronto, he joined the chemistry faculty of Brooklyn Poly in 1978, and served as Department Chair from 2006-2012.  After the merger between NYU and Poly, he became a member and Associate Chair of the Chemical and Biomolecular Engineering Department.  He has published over 80 research articles and holds 5 patents.  He is the recipient of an Alfred P. Sloan Research Fellowship and is a two-time recipient of the Polytechnic Distinguished Teacher Award.  

His research group currently studies two aspects of the way light interacts with materials:  laser light scattering and laser-induced nucleation.  They use depolarized light scattering to probe the micrometer-scale grain structure of block copolymer materials, which have important applications as viscoelastic, adhesive, optical and electrical materials.  Recently, they have begun to study the integrated static light scattering from polymer blends to determine their miscibility.  Such blends have potential application as lithium battery electrolytes. They use high-power, pulsed laser beams to non-photochemically initiate the nucleation of supersaturated solutions, and they are currently collaborating with Prof. Ryan Hartman to study laser-induced nucleation in microfluidic devices. Crystallization is an important process in the chemical and pharmaceutical industry where control of crystal size, morphology and polymorphism are crucial in producing products with the desired properties.
