Bob McCullough is currently Emeritus Professor of Atomic Physics and a visiting research Fellow in the Centre for Plasma Physics with more than 30 years experience in the field of low energy ion interactions with atoms and molecules. His work, both fundamental and applied, supported by the EPSRC, The European Community and the British Council Academic Research Collaboration (ARC) programmes, has been predominantly in the area of ion collision physics, relevant to astrophysical and technological plasma environments, with pioneering studies of state selective electron capture (SSEC) in the interaction of low energy (<1 keV amu-1) multiply charged ions with atomic and molecular hydrogen and other more complex systems. His group at Queen’s University has provided a unique UK contribution to the field of low energy ion-atom/molecule electron capture interactions and have pioneered a technique for studies with state prepared ions. Recent work, in collaboration with international colleagues, studied the interaction of low energy ions with molecules relevant to biological and cometary environments. He has developed sources for multiply charged ions and reactive atom sources that have found applications in astrochemistry experiments and semiconductor technology and is currently being used in the ASACUSA (http://asacusa.web.cern.ch/ASACUSA/) collaboration at CERN for low energy antiproton ionisation experiments.
He is a former chair of the Institute of Physics in Ireland and of the Institute of Physics Atomic and Molecular Interactions Group (AMIG) and was a member of the executive committee of the recently completed successful EC Integrated Infrastructure Initiative (I3) ITS-LEIF consortium (www.its-leif.org).
