My research is focused on the investigation of fundamental nuclear properties, and specifically masses and radii. The work involves laser spectroscopy experiments for the determination of changes in nuclear charge radii over long isotopic chains as well as nuclear mass measurements using Penning traps.

Our principle experiments are the Canadian Penning Trap experiment at Argonne National Laboratory, the TITAN Penning Trap experiment at TRIUMF and the Collinear Laser Spectroscopy Experiment at TRIUMF. The experiments determine moments, radii and masses of nuclei far from stability and provide data for nuclei of relevance in stellar processes and for the refinement of nuclear models, in general.

Other areas of interest include the application of research methods to technical challenges (`Applied Physics'). Specifically:

• RFQ-ion traps and lasers are used for the detection of low abundance species and for manipulating atoms on nanoscopic scales.
• The creation of defects in avalanche photodiodes by single neutrons allows time-resolved studies of defect generation and annealing with ms resolution.
