  • Profile

    Professor Cowin has also been Professor-in-Charge of the Tulane/Newcomb Junior Year Abroad Program in Great Britain and Chairman of the Applied Mathematics Program at Tulane. In 1985 he received the Society of Tulane Engineers and Lee H. Johnson Award for Teaching Excellence. He was also the recipient of the Best Paper Award from the Bioengineering Division of the American Society of Mechanical Engineers in 1992; a recipient of the Melville Medal from the American Society of Mechanical Engineers in 1993, and a recipient of the European Society of Biomechanics Research Award in 1994. In 1999 he receive the H. R. Lissner medal of the American Society of Mechanical Engineers for contributions to biomedical engineering. In 2004 he was elected to the National Academy of Engineering. In 2004 he also received the Maurice A. Biot medal of the American Society of Civil Engineers.

  • Research Interests

    Mechanics of materials, particularly in the determination of the influence of microstructure on the gross mechanical behavior of granular, composite, and biological materials; 
Current publications are in orthopedic biomechanics and anisotropic elasticity.
Professor Cowin also serves as an Adjunct Professor of Orthopedics at the Mt. Sinai School of Medicine in New York City . He is the author of over two hundred research papers, editor or co-editor of five books and coauthor of a textbook on Tissue Mechanics. He is presently or has been an Associate Editor of the Journal of Applied Mechanics and the Journal of Biomechanical Engineering, a member of the Editorial Board of the Annals of Biomedical Engineering and the Editorial Advisory Board of the Handbook of Bioengineering and the Handbook of Mechanics, Materials, and Structures and the International Journal of Biomechanics and Modeling in Mechanobiology. Professor Cowin is known for his analysis of static bin pressure induced by granular materials, his development of a continuum theory for granular materials (with M. A. Goodman), the creation of the continuum theory of materials with small voids (with J. W. Nunziato), for the development of models of granular material slip zones (with M. M. Mehrabadi), basic theorems in anisotropic elasticity (with M. M. Mehrabadi) and the development of the bone remodeling theories and computational algorithms with many co- investigators over a thirty-five year period. For many years he worked with Shelly Weinbaum to develop a physiological model for mechanotransduction in living bone. His current interest is in fluid movement in bone and soft tissue, developmental biology and anisotropy of materials.
