Areas of interest
Dr Hallett’s current research interests involve the role of specific electrolytes in the structure and morphology of soft matter systems, such as films, membranes and gels.
These materials are studied using a variety of techniques, including 3D microscopy, surface force measurements and surface pressure measurements of supported films. He also has a longstanding interest in the use of X-ray and Neutron techniques at large facilities (Diamond, ISIS, ILL, MAXLAB, ESRF) to study soft matter systems.
Research centres and groups
Dr Hallett is part of the Soft Matter research group.
BackgroundDr Hallett was appointed as a Lecturer in November 2021. Prior to that he was a Stipendiary Lecturer in Physical Chemistry for Trinity College Oxford and senior postdoctoral researcher working in the group of Professor Susan Perkin (University of Oxford, Physical and Theoretical Chemistry), starting in February 2018. Prior to this he was a postdoctoral researcher in the group of Professor Paddy Royall at The University of Bristol (Physics) using dense suspensions of nanoparticles to study the phenomenology of vitrification and gelation.
He undertook his PhD studies under the supervision of Professors Paul Bartlett and Robert Richardson at the University of Bristol (chemistry), studying colloidal and liquid crystal systems for energy-efficient display applications.
