CFN Research Activities

Kevin’s research program includes materials science and measurement science aspects. His materials science research focuses on the self-assembly of soft materials, especially in terms of how non-equilibrium phenomena and pathway-dependent ordering can be exploited in order to generate complex 'non-native' morphologies. His measurement science research focuses on x-ray scattering, especially the development of new techniques suited to studying nanomaterials. Kevin has worked with collaborators to study a wide variety of materials, including block-copolymers, nanoparticle superlattices, organic photo-voltaics, and liquid crystals. Kevin is currently developing autonomous scientific instruments, including deploying robotics and machine-learning at synchrotron beamlines to allow autonomous materials discovery.
