Chair: Olivier Delaire

Associate Professor of Mechanical Engineering and Materials Science and Physics
Duke University
Term expires December 2022

 

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.

 

 

 

Vice Chair: Martin Mourigal

Assistant Professor of Physics
Georgia Institute of Technology
Term expires December 2022

 

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.

Former Chair: Michelle Dolgos

Assistant Professor
Oregon State University
Term expires December 2019

 

Research interests: solid state chemistry and her research area can be broadly defined as investigating structure-property relationships in advanced functional materials. Her particular focus is in two areas of materials chemistry: 1) elucidating the structure-property relationships of lead-freepiezoelectric materials and 2) structural studies of amorphous and nanocrystalline materials for electronic applications.

 

 

Secretary: Adam Aczel

Staff Scientist
Oak Ridge National Laboratory
High Flux Isotope Reactor
Term expires December 2020

 

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

Allyson Fry

Allyson Fry-Petit

Professor of Chemistry
California State University Fullerton, Fullerton, CA
Term expires December 2020

 

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.

 

Sudipta Gupta

Post. Doc. Fellow
Department of Chemistry
Louisiana State University
Term expires December 2019

 

Research interests: constrained structure and dynamics in soft matter, including complex fluids like synthetic polymers, biological macromolecules, colloids, glasses and polymer nano-composites.

 

 

Jarek Majewski

Program Director
National Science Foundation
Term expires December 2022

 

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.
