Ashley Peter Williams

Ashley Peter Williams is a Soft Matter Scientist at the Paul Scherrer Institute (PSI) in Switzerland, working at the Laboratory for Neutron Scattering and Imaging (LNS) on the SANS-I instrument. He holds a PhD from Monash University in Australia with a thesis focused on "Surfactant Design for Wormlike Micelles" and previously completed Honours research on developing SANS models for concentrated wormlike micellar systems.

His research centers on understanding the behavior of soft, colloidal materials with particular emphasis on molecular design to manipulate behaviors like the self-assembly of surfactant molecules and the gelation and relaxation of nanoparticles. His work has significant implications for cosmetics, personal care products, and the utilization of cellulose as a renewable and sustainable nanomaterial to modify flow and rheology.

Williams' publications reveal a strong focus on surfactant chemistry, micellar structures, and rheological properties. His recent work examines how different cations affect the rheological properties of surfactant mixtures, with implications for targeted delivery systems. His research employs advanced techniques including small-angle neutron scattering (SANS), small-angle X-ray scattering (SAXS), and cryogenic electron microscopy (cryo-EM) to investigate the nanostructural properties of complex fluids.

His scientific contributions span multiple high-impact journals including Langmuir, Small Methods, Journal of Physical Chemistry B, and Advances in Colloid and Interface Science, demonstrating expertise in both fundamental soft matter physics and practical applications in consumer products and sustainable materials.
