Masa Fukuto 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, and phase behavior and structures of lipid membranes. His current research aims to understand and control interfacial self-assembly of biomolecular and inorganic nano-objects, such as proteins, viruses, and nanoparticles.
At NSLS II, Masa leads the operation and development of the Complex Materials Scattering (CMS) beamline, a three-pole wiggler beamline that provides SAXS/WAXS and GISAXS/GIWAXS capabilities. CMS is dedicated to studies of the bulk and interfacial structures of complex materials of interest to the materials science community.
