Current members of the Disordered Materials group




Group Leader
​ ​​​ ​

​​​​Daniel first joined ISIS in 2000 as the instrument scientist responsible for SANDALS. In 2007, he was appointed as the project scientist for NIMROD, and in 2009 was promoted to Group Leader. Daniel's science interests are focussed on atomic and mesoscale structure-property relationships in a broad range of liquids and amorphous materials. He also develops instrumentation and analysis techniques for neutron and X-ray diffraction, X-ray Absorption Spectroscopy, and atomistic computer modelling.

GEM​ Instrument Scientist

Alex joined ISIS in 1986 as an inst​​rument scientist on POLARIS, which was then a beamline for the development of beam polarisation techniques. In 1988 he became an instrument scientist on LAD, the forerunner of GEM. He has been a member of the group since 1997, and he has been responsible for the Disordered Materials programme on GEM since it started operation in 1999. His personal research interests are focussed on the structure of glasses and disordered crystals, with an underlying aim to understand how the bonding between atoms works in glasses.

Dr ​Oliver Alderman
SANDALS Instrument Scientist

Oliver joined ISIS in 2019 as an instrument scientist on SANDALS. His research interests include structure-property relationships in oxide glasses, melts and supercooled liquids, particularly ​the temperature dependent structural changes accompanying glass formation, or those induced by redox reactions. He has expertise in neutron and x-ray diffraction from amorphous materials, especially oxides, including the generation of experimentally constrained atomistic models by Empirical Potential Structure Refinement and classical molecular dynamics simulations.​

SANDALS​ Instrument Scientist

Terri-Louise joined ISIS in 2022 as a SANDALS instrument scientist. Her background is in chemistry and catalysis. During her PhD she used operando NMR and total neutron scattering on NIMROD to study heterogeneously catalysed reactions and confined liquid mixtures.

Dr Tom Headen
NIMROD Instrument Scientist

Tom joined ISIS in 2015 as an instrument scientist on NIMROD. His research interests centre on structural studi​​​es of aromatic liquids and solutions, from applied systems such as crude oil asphaltenes to fundamental studies of simple aromatics such as benzene and toluene. He has expertise in analysis of small-angle neutron scattering data and using molecular dynamics simulations to study aggregating systems.

​Prof. Alan Soper
Emeritus STFC Senior Fellow

Alan first joined ISIS in 1986 as an instrument scientist supporting LAD, and in 1997 formally established the Disordered Materials Group within the facility. Within his career he has played a leading role in the design of the SANDALS, GEM and NIMROD diffractometers, and delivered internationally renowned data analysis software for processing and modelling neutron and X-ray diffraction data of liquids and glassy materials: Gudrun, and Empirical Potential Structure Refinement. Alan is arguably the world expert on the molecular scale structure and properties of liquid water and aqueous solutions, but has wide-ranging interests across the entire field of liquids and disordered materials research. In 2014 he was awarded FRS for his contributions to the study of disordered materials.

NIMROD Instrument Scientist

Tristan joined the Disordered Materials group in 2012 as instrument scientist for NIMROD. His principal research interests foc​us on confined molecular and ionic liquids, the application of neutron scattering to heterogeneous catalysis (for which he is in​dustrial liaison for the group), and the development of computational tools to assist in the analysis and modelling of data.​
