Instrument scientist, NIST Center for Neutron Research (NCNR) Research interests: neutron/x-ray scattering techniques and theories, biophysics, colloidal science, energy materials, and gas adsorption/desorption in porous materials. |
Physicist Research interests: Strongly correlated electrons and quantum magnetism; lattice dynamics in perovskites; developing novel neutron instrumentation and methods.

Assistant Professor of Physics Research interests: Structure-property relationships in soft matter, with specific emphasis on polymeric systems and biomimetic lipid membranes. Dr. Ashkar's group is primarily focused on advancing the use of neutron scattering, in conjunction with simulations, to resolve collective structures and dynamics that are critical to the fundamental understanding and practical applications of soft materials. |
Director, Robert A. W. Carleton Strength of Materials Laboratory Adjunct Assistant Professor, Civil Engineering and Engineering Mechanics, Columbia University 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.

|
|
Instrument Scientist Research interests: Using x-ray and neutron scattering techniques to study correlated electron materials, topological magentism, and structure-property relationships. |
Instrument Scientist at the High Flux Isotope Reactor (GP-SANS) Research interests: Flux-line lattices in unconventional superconductors; magnetism in small-angle neutron scattering; probing long-range magnetic order in materials with rich magnetic phase diagrams and structural ordering in other systems with large scale spacings in on or more dimensions using SANS and related techniques.
|
|
|
NRC Research Associate Research interests: Understanding the role of orientation and alignment in determining soft matter properties; connecting SANS anisotropy to material alignment and mechanical performance.
|
Assistant Professor of Chemistry and Biochemistry 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. |
|
|
Instrument Scientist Research interests: Exploring the structure and dynamics of energy-related materials to relate their structure-property realtionship to their real-life application, especially of thenano-confided fluids, polymers, and polymer nanocomposites.
|
Assistant Professor of Materials Science and Engineering 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. |
|
|
Instrument Scientist at the High Flux Isotope Reactor (HB1, HB3, CTAX) Research interests: Heavy fermion systems, particularly the hidden order system URu2Si2 and the cerium-based non-centrosymmetric magnets CeTX3; materials synthesis and experiments using muon spectroscopy. |
Assistant Professor Research interests: Using biophysical characterisation methods, especially SANS, to study how biomacromolecules behave and interact in crowded environments. |
