Bio

Prof. Rollett has been a Professor of Materials Science & Engineering at Carnegie Mellon University since 1995 and before that was with the Los Alamos National Laboratory. His most recent honors were the Member of Honor of the French Society of Materials (SF2M) in 2015, the Edgar C. Bain Award from the Pittsburgh Chapter of ASM International in 2016, and the appointment as US Steel Professor of Metallurgical Engineering & Materials Science at Carnegie Mellon University in 2017. He is a member of the Basic Energy Science Advisory Committee and the Defense Programs Advisory Committee (Dept. of Energy).

Education

M.A., Cambridge University (UK)
Ph.D., Drexel University

Research

Rollett's research focuses on microstructural evolution and microstructure-property relationships in 3D, using both experiments and simulations. Interests include 3D printing of metals, materials for energy conversion systems, strength of materials, constitutive relations, microstructure, texture, anisotropy, grain growth, recrystallization, formability and stereology. Relevant techniques highlight spectral methods in micro-mechanics, Dynamic X-ray Radiography and High Energy Diffraction Microscopy. Important recent results include definition of process windows in 3D printing through characterization of porosity, 3D comparisons of experiment and simulation for plastic deformation in metals, the appearance of new grains during grain growth, and grain size stabilization.
