| 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 instrument 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
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.

| Dr Tom Headen
Tom joined ISIS in 2015 as an instrument scientist on NIMROD. His research interests centre on structural studies 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.

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 Hima Bindu KolliAda Lovelace Centre Software Engineer
Bindu joined ISIS in 2020 as a computational chemist, working as lead developer on the Multi-scale Simulation Scattering Intensity Calculator (MuSSIC) project, funded by the Ada Lovelace Centre. The MuSSIC project aims to expand the lengthscales accessible to simulation-based data refinement techniques leveraged by the Disordered Materials group through a variety of coarse-graining techniques.

Prof. Alan Soper STFC Honorary Scientist
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, and is currently a retained consultant within ISIS.

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

Associated Members

| Dr Marta Falkowska
University of Manchester at Harwell (UoMaH) Fellow
Marta was awarded Dame Kathleen Ollerenshaw Fellowship of the University of Manchester in 2022. Her interests are focused around understanding liquids and fluids confined within porous materials on macroscopic and molecular levels. The systems under her investigations span from reagents in catalyst pores through solutions separated by MOFs to preferential gas adsorption on molecular sieves. As a Harwell Fellow associated with the Disordered Materials Group at ISIS, Marta aims to promote and increase the use of total neutron scattering techniques by researchers at the University of Manchester.
