Awarded Distinguished Service Award 2001

Fellow, Elected 2015

Dr. Andrew “Andy” Kraynik received his undergraduate degree from Carnegie Mellon University in 1972. He received his Ph.D. from Princeton in 1976 where he worked with William R Schowalter (1988 Bingham Medalist). He worked at Sandia National Laboratories in Albuquerque, New Mexico until retirement in 2011 as a Principal Member of Technical Staff.

Dr. Kraynik is internationally known as the leading authority on the structure and rheology of foams and the processing of these complex, multicomponent systems. In his research he studied the structure and deformation of a wide range of foam and emulsion systems, and the structure of random foams as well as many other structural components. He also applied these ideas to studies of the morphology of bone scaffolds. The Kraynik-Reinelt unit cell and associated periodic boundary conditions are still widely used in the scientific community to enable numerical simulations of planar elongational deformations at large strains.

Dr. Kraynik has extensively served The Society of Rheology, including as Secretary from 1989-1999. He organized and hosted the 62nd and 82nd Annual Meetings of The Society of Rheology in 1990 and 2010 in Santa Fe, and helped Gerry Fuller organize the XVth International Congress on Rheology and 80th Annual Meeting of The Society of Rheology in Monterey, California, in 2008. He also served as US Delegate to the International Committee on Rheology. He was awarded the Society’s Distinguished Service Award in 2001, which is given out rarely and at the discretion of the Executive Committee. He was then elected as the President of the Society from 2005-2007 and continues to serve the Society as the Annual Meetings coordinator and liaison to the Executive Committee. He has attended every annual meeting of the Society since 1977. An avid birder, Andy has made several trips to South and Central America since retiring.
