About
Rollett's research focuses on the science of additive manufacturing, 3D printed heat exchangers, microstructural evolution and microstructure-property relationships in 3D. Interests include microstructure control in 3D printing of metals, materials for energy conversion systems, strength of materials, constitutive relations, microstructure, texture, anisotropy, grain growth, recrystallization, formability, extreme value statistics and stereology. Important recent results include relating fatigue performance in printed Ti-6Al-4V to LPBF parameters, machine learning to predict porosity development with synchrotron visualization as ground truth, development of a spectral approach to eigenstrain problems, validation of the 3D elasto-viscoplastic FFT code against synchrotron x-ray diffraction data, prediction of solidification microstructure, the appearance of new grains during grain growth, and grain size stabilization. He is the U.S. Steel Professor of Metallurgical Engineering and Materials Science at Carnegie Mellon University and before 1995 was with the Los Alamos National Laboratory. He is a Fellow of several professional societies. He is the co-Director of CMU’s NextManufacturing Center that is dedicated to advancing manufacturing especially through 3D printing of metals. He has over 300 peer-reviewed publications. Rollett is mostly closely aligned with CDAC Thrust I. Thermomechanical Extremes.
