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 (DOE Early Career Award 2014). His research group studies  elementary excitations in condensed-matter systems (phonons, electrons, spins), their couplings (phonon-phonon interaction, electron-phonon coupling, spin-phonon coupling), and their effects on macroscopic material properties. Current materials of interest include thermoelectrics, ferroelectrics/multiferroics, spin-caloritronics, and photovoltaics. We develop 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 with novel properties (thermoelectrics, spin-caloritronics), and to rationalize multiferroics and metal-insulator transitions. 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 is an expert in the field of atomic dynamics in materials, with 15-plus years of experience in both experimental and computational studies of lattice dynamics (phonons).
