Patrick T. MacGregor is a nuclear-structure physicist, probing exotic nuclear systems primarily using transfer reactions. He completed his PhD in experimental nuclear physics at The University of Manchester in 2021, investigating the single-particle structure of the neutron-rich 29Mg, the results of which are written in this volume. This details the results from the first experiment at the ISOLDE Solenoidal Spectrometer (ISS), a novel device at the CERN facility that is able to study exotic nuclear systems. This work was published in Physical Review C 104, L051301 (2021). He is an experienced user of this device, and has supported other experimental campaigns that use it (see, for example, T. L. Tang et al., Physical Review Letters 124, 062502 (2020)). Currently, he is pursuing postdoctoral research using transfer reactions to extract the occupancies and vacancies of the A=124 neutrinoless double beta decay system. Additionally, he is continuing his research on the magnesium isotopes by analysing data from an analagous reaction performed at the ISS to investigate the single-particle structure of 31Mg. Outside of work, he enjoys spending time with his wife, Ally, who has brought colour to his otherwise boring lifestyle.
