Masa is the Lead Scientist for the Complex Materials Scattering (CMS) beamline and also serves as the interim Program Manager for the Complex Scattering Program, which operates a suite of scattering beamlines at National Synchrotron Light Source II. The Complex Scattering Program’s mission is to develop cutting-edge x-ray scattering techniques to advance scientific understanding of the spatiotemporal behavior of complex soft, hard, and bio materials to drive transformative discoveries by optimizing material synthesis and processing conditions as well as material behavior under extreme conditions for applications that impact the national health, energy and environmental security. The CMS beamline provides (GI)SAXS/WAXS capabilities to facilitate studies of bulk and interfacial material structures of interest to the materials science community.

Research Activities

Masa has been using x-ray scattering to study interfacial phenomena in a variety of soft matter systems. These studies include in situ x-ray measurements of capillary-wave fluctuations at liquid interfaces, short-range order and inhomogeneities in Langmuir films, critical Casimir forces in binary wetting films, interfacial and confinement effects on liquid crystals, phase behavior and structures of lipid membranes, and interfacial self-assembly of biomolecular and inorganic nano-objects, such as proteins, viruses, and nanoparticles. He is also working with collaborators on the development and application of autonomous experimentation methods for synchrotron beamline experiments.
