Felix is the leader of the ISIS Molecular Spectroscopy Group. The group is responsible for the science and instrumentation programmes on a suite of high-resolution neutron spectrometers spanning ca. eight orders of magnitude in timescales, from stochastic diffusion or quantum tunnelling at THz and sub-THz frequencies to nuclear quantum dynamics using deep-inelastic neutron scattering techniques. These experimental capabilities remain unique to the ISIS instrument suite, with a growing number of applications in physical and materials chemistry, industrial catalysis, energy research, etc.
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
Being the lightest and most abundant of all chemical elements, Felix has had a lifelong passion for the rich and complex physical chemistry of hydrogen in a number of situations of fundamental and practical interest. These have ranged from detailed studies of chemical reactivity using velocity-sensitive laser spectroscopy and ion-imaging techniques [1-3], to the dynamics of hydrogen bonds in strongly associated liquids  or nuclear quantum effects in the solid molecular hydrogens  using high-resolution and spin-echo inelastic neutron scattering. On a more applied front, current research projects include the study of molecular [6-8] and supramolecular [9-10] uptake and intercalation in nanostructured and soft layered materials [11-12], and proton dynamics, transfer, and conduction mechanisms in functional and technological materials . This research programme makes extensive use of computational modelling tools in parallel with experiment, as most recently illustrated by ongoing developments in mass-selective neutron spectroscopy and quantum thermometry of light nuclides beyond the proton [14-15]. With D.L. Price, he is editor of a new book series on the fundamentals and applications of Neutron Scattering.
Since joining ISIS, Felix has participated in a number of infrastructure developments on both Target Stations, including recent and ongoing upgrades of IRIS, OSIRIS, and TOSCA. Beyond ISIS, Felix has been actively engaged in the design and specification of the first Spanish accelerator-driven neutron source .
