Felix is the leader of the ISIS Molecular Spectroscopy Group. His group is responsible for the science and instrumentation programmes on a growing suite of high-resolution neutron spectrometers spanning ca. eight orders of magnitude in timescales, from stochastic diffusion and quantum tunnelling at THz and sub-THz frequencies to nuclear quantum dynamics using mass-resolved spectroscopic techniques. These experimental capabilities remain unique to ISIS, with an increasing number of applications in physical and materials chemistry, catalysis, and energy research. For a recent overview of these research activities, see the proceedings of the latest Molecular Spectroscopy Science Meeting.
Felix is also the coordinator of the Centre for Molecular Structure and Dynamics, a research network funded and managed by the Science and Technology Facilities Council to bring together expertise in Molecular Science across STFC departments and external stakeholders from academia and industry.
Research and development interests
With a primary focus on the discovery of novel materials for energy applications using state-of-the-art radiation-scattering techniques, current research projects range from molecular [1-4] and supramolecular [5-6] uptake and intercalation in nanostructured and soft layered media [7-8], to proton-conduction and energy storage in carbon-based materials [9-10]. This research programme makes extensive use of computational materials modelling in parallel with experiment, as best illustrated by ongoing developments in mass-selective neutron spectroscopy [11-12]. Fundamental studies underpinning the above themes include hydrogen bonding in strongly associated liquids  and nuclear quantum dynamics using high-resolution and spin-echo neutron spectroscopies [9,14]. As a physical chemist, Felix has also made pioneering contributions to our understanding of chemical reactivity using velocity-sensitive laser spectroscopy and ion-imaging techniques [15-17].
At present, Felix leads a number of projects at ISIS, including ongoing developments on IRIS & OSIRIS, TOSCA, and VESUVIO. Beyond ISIS, Felix continues to champion the application of neutron scattering in physical and materials chemistry [18-19], and has also been engaged in the design and specification of the first Spanish accelerator-driven neutron source for materials research [20-22]. With D.L. Price, he is editor of a new book series on the fundamentals and applications of neutron scattering [23-25].
