Research Interests
Research interests are in the general area of inorganic surface chemistry. Current research projects focus on adhesive bonding of polymeric materials and metals. Research accomplishments in the area of adhesion have resulted in obtaining an understanding the role of surface treatment on bond failure in durability studies of adhesively bonded polymer-polymer, polymer-metal, and metal-metal systems. Fundamental studies of the acid-base interactions at the adhesive-adherend interface in durability experiments have resulted in a better understanding of the failure processes.
