Here, we shall discuss an alternative in which imposed shear flows can delay or eliminate interfacial instabilities though the shear triggers others that are less 'harmful.' This will be illustrated by the suppression of Van der Waals rupture instability in ultra-thin liquid films. --------------------------------------------------------------------------------BIO:Stephen H. Davis received all his degrees at Rensselaer Polytechnic. He has been Research Mathematician at the RAND Corporation, Lecturer in Mathematics at Imperial College, London, and Assistant, Associate Professor and Full Professor of Mechanics at the Johns Hopkins University. He is Editor of the Journal of Fluid Mechanics and the Annual Review of Fluid Mechanics. He has authored 200 refereed technical papers in the fields of Fluid Mechanics and Materials Science and the book Theory of Solidification. He has twice been Chairman of the Division of Fluid Dynamics of the American Physical Society, is a Fellow of the American Physical Society, is a member of the National Academy of Sciences, the National Academy of Engineering, and the American Academy of Arts and Sciences, and was the 1994 recipient of the Fluid Dynamics Prize of the APS and the 2001 G. I. Taylor Medal of the Society of Engineering Science.
