Research Interests

My professional life has been focused on the development of scientific instrumentation since the final year of my Bachelor degree nearly 15 years ago. I have been involved in a number of neutron and syncrotron instrumentation projects in the UK, DE, DK and SE over the years. I have taken a leading role in developing the concept of the neutron backscattering spectrometer MIRACLES for the European Spallation Souce (ESS) until early 2015 together with Ruep Lechner and Heloisa N. Bordallo. My interests of instrument development also permeated my scientific research and when time permits I take part in the publication of scientific papers based on quasielastic scattering (QENS) with my collaborators.

My current role in the neutron chopper group is focused on SSM licensing in terms of safety, planning of installation and maintainance acitivites, gaining access to external grants and collaborative projects and netron scattering instrument support.
