Research Interests

Microstructure-property relationships in crystallographically textured materials Grain boundaries, their anisotropic properties and their impact on microstructural evolution Grain growth and recrystallization Computer simulation of microstructural evolution and properties of materials Statistical methods for describing and constructing microstructures in three dimensions Texture- and interface- sensitive properties, e.g. strength, fatigue resistance.

Biography

Professor Rollett obtained an M.A. in Metallurgy and Materials Science from Cambridge University, England in 1977 and a Ph.D. in Materials Engineering from Drexel University in 1987. He worked for the Los Alamos National Laboratory for sixteen years, rising to be the Deputy Director of the Materials Science & Technology Division in 1994. He then moved to CMU to be the Department Head in Materials Science & Engineering which position he occupied from 1995 to 2000. He became a Fellow of ASM International in 1996. He is active in the Materials Research Science & Engineering Center at CMU; is the Focal Area Point of Contact for Computational Chemistry & Materials for the DoD; is the Chair of the International Committee for the Conference on Recrytallization and Grain Growth; and, helps to run a project in the DOE Computational Materials Science Network.
