Kevin Yager is a materials scientist and group leader at Brookhaven National Laboratory, working in the Center for Functional Nanomaterials (CFN). He participated in the conception, design, and construction of next-generation beamlines at NSLS-II; specifically the Complex Materials Scattering (CMS) and Soft Matter Interfaces (SMI) beamlines.

Kevin is active on this site (User:KevinYager), and is happy to answer questions about x-ray scattering experiments or data analysis.

Scattering Expertise

Kevin has worked as a beamline scientist on the X9 beamline at NSLS, where he helped users perform a wide variety of x-ray scattering experiments (SAXS, WAXS, GISAXS, GIWAXS). Kevin has also used neutron techniques, including neutron scattering (SANS, GISANS, RSANS) and neutron reflectivity (NR). He was involved in the development of the GTSAXS technique.

He is actively involved in developing new models for analyzing and fitting x-ray scattering data; e.g. he recently developed a formalism for handling data from lattices of nano-objects (c.f. summary of paper.). He is also interested in the application of Artificial Intelligence and Machine-Learning (AI/ML) methods to synchrotron beamlines; in particular working with a team that is deploying Autonomous Experimentation at beamlines.

Scientific Interests

Kevin is interested in soft materials and self-assembly. In particular, he has worked on problems in block-copolymers (fundamental physics, directed assembly, nonequilibrium ordering, etc.), organic photo-voltaics, and nanoparticle superlattices.
