ProfileRuth Stark received her A.B. degree in Chemistry at Cornell University and obtained her Ph.D. in Physical Chemistry at the University of California, San Diego. A CUNY faculty member since 1985, Dr. Stark was designated as Distinguished Professor in 2006 and elected as a Fellow of the American Association for the Advancement of Science in 2010. Currently, she directs the 8-campus CUNY Institute for Macromolecular Assemblies (MMA) and CCNY's Graduate Assistance in Areas of National Need (GAANN) program. Drawing on training at the interface of chemistry, physics, and biology, her current research program focuses on the molecular structure and development of biopolymers that protect fruits and vegetables, the solution-state structure and functional regulation of nutritionally important fatty acid-binding proteins,and the molecular development of melanin pigments associated with human fungal infections. Professor Stark has supervised more than 100 research trainees from high school through postdoctoral levels, including 45 women and 20 underrepresented minorities.

Research InterestsThe Stark Laboratory uses structural biology approaches to study plant protective polymers, lipid metabolism, and potentially pathogenic melanized fungal cells. Nondestructive study of the molecular and mesoscopic architectures underlying the integrity of cuticles in natural and engineered tomatoes and potatoes is undertaken using solid-state nuclear magnetic resonance (NMR), mass spectrometry, atomic force microscopy, and multivariate statistical methods. Ligand recognition and peroxisome proliferator-activated receptor interactions of fatty acid-binding proteins are under investigation by molecular biology and solution-state NMR. The molecular structure and development of melanin pigments within fungal cells is probed using (bio)chemical synthesis and solid-state NMR.
