Ralph H. Colby received his B.S. in Materials Science and Engineering from Cornell University in 1979. After working
for two years at the General Electric Company in rheology research and process development, he attended
graduate school at Northwestern University, where he received his M.S. and Ph.D. in Chemical Engineering in 1983
and 1985. Graduate research focused on rheology of linear polybutadiene melts and solutions, and included 15
months as a visiting scholar in the Exxon Research and Engineering Company, Corporate Research - Science
Laboratories. He then worked for ten years at the Eastman Kodak Company in their Corporate Research
Laboratories. Rheology research areas over these ten years included linear polymer melts and solutions, miscible
polymer blends, block copolymers, randomly branched polymers, gels, liquid crystalline polymers, polyelectrolytes,
proteins, surfactants and colloidal suspensions.
In 1995, Dr. Colby was hired as Associate Professor of Materials Science and Engineering at the Pennsylvania State
University and was promoted to Professor in 2000. He teaches a demanding undergraduate course on Polymer
Rheology and Processing and continues rheological experiments to probe the dynamics of polymers and other
complex fluids. He has over 150 publications and published a textbook Polymer Physics in 2003. He was a Fulbright
Scholar in New Zealand in 2005 and is currently a Leverhulme Visiting Professor at Imperial College, London in
2012.
