Olivier Delaire
Associate Professor of Mechanical Engineering and Materials Science

Olivier Delaire's research program investigates atomistic transport processes of energy and charge, and thermodynamics in energy materials. The nanoscale studies probe atomic dynamics and elementary excitations in condensed-matter systems (phonons, electrons, spins), their couplings and their effects on macroscopic material properties. Current materials of interest include thermoelectrics, ferroelectrics/multiferroics, spin-caloritronics, and photovoltaics. The Delaire group develops new methods to reveal microscopic underpinnings of thermal transport, by integrating neutron and x-ray scattering measurements with quantum-mechanical computer simulations. This combined experimental and computational approach opens a new window to understand and control microscopic energy transport for the design of materials enabling novel technologies for energy applications (thermoelectrics, solid-state batteries, photovoltaics) and information storage and processing (multiferroics, metal-insulator transitions, topological materials). In addition to state-of-the-art scattering experiments and first-principles simulations, our team also uses transport measurements, optical spectroscopy, materials synthesis, calorimetry, and thermal characterization, with the goal of gaining deeper atomistic understanding for developing future materials.

Current Research Interests

Olivier Delaire investigates atomic dynamics in materials, focusing on problems at the interface of Materials Science, Physics and Chemistry. His research group utilizes a range of experimental and computational approaches, including neutron and x-ray scattering techniques, optical spectroscopy, and first-principles quantum materials simulations.
