Chair: Martin Mourigal Assistant Professor of Physics
Research interests: The magnetic dynamics of quantum antiferromagnets and spin-liquids. In his laboratory at Georgia Tech, students and postdocs engage in a broad portfolio of quantum materials techniques, including sample synthesis and characterization, inelastic neutron scattering, and theoretical modelling.
|
Past Chair: Olivier Delaire Associate Professor of Mechanical Engineering and Materials Science and Physics
Research interests: Lattice dynamics in solid materials, in particular the effects of phonon anharmonicity, electron-phonon coupling and spin-phonon coupling. His group makes extensive use of both neutron and x-ray scattering, coupled with first-principles computer simulations to rationalize experimental data and predict material responses.

Director, Robert A. W. Carleton Strength of Materials Laboratory
Research interests: Neutron scattering measurements in infrastructure components, packing mechanics, residual stress and contact force mapping of multibody systems, characterization of materials under high temperature (fire), eigenstrain analysis of complex geometries, and curing dynamics of cementitious materials and composites.
|
Secretary: Adam Aczel Staff Scientist
Research interests: Neutron scattering and muon spin relaxation studies of quantum materials, with a current emphasis on frustrated magnetism, skyrmions, and heavy transition metal magnets.

Professor of Chemistry
Research interests are in solid state inorganic chemistry, focused on the rational design of new materials through the use of data mining, synthesis, structural characterization and spectroscopy. Her lab is also working on the analysis of dynamic pair distribution function data from inelastic neutron scattering.
|
Research interests: The Shoemaker Group focuses on discovery and characterization of new electronic and magnetic materials. Neutron-related research includes structure solution, magnetic dynamics, in situ measurements of synthesis and phase transitions, and local structure analysis.

Program Director
Research interests: Jarek is currently a program director at the Molecular Biophysics Cluster in the Division of Molecular and Cellular Biology at the National Science Foundation. He is on a leave of absence from Los Alamos National Laboratory where, over the past 20 years, he has built a successful x-ray and neutron scattering program to address interfacial structures and properties of materials.
|
Instrument Scientist
Research interests: Microscopic dynamics in broadly defined soft matter, from simple and complex fluids to cells and organisms.
|
|
|
Professor of Chemistry and Physics
Research interests: Complex fluids and polymers, elastic and quasi-elastic neutron scattering and large-scale MD simulations
|
Research interests: Understanding the structure—property relationships of inorganic solid state materials, particularly those of relevance to energy and electronics-related technology. Research focuses on solid state synthesis and characterization techniques with an emphasis on neutron and synchrotron X-ray total scattering to gain a detailed understanding of the structure of a material.
|
|
|
Research interest: Understanding emergent phenomena in quantum materials with a current emphasis on frustrated magnetism in rare-earth based materials. Using neutron scattering to probe magnetic structures and spin dynamics on very small samples.
