After undertaking undergraduate studies at the University of Waikato and an MSc at the University of Auckland, I completed my PhD at the Australian National University. After postdoctoral positions at the CSIRO and ANU I started work as lecturer at Otago in 2007.

The main theme of my research has been studying how defects and impurities
in solids interact with light. In particular I have investigated the
benefits of rare earth ion dopants as alternatives to trapped atomic
systems for quantum information processing applications. I am also investigating applications of these systems outside quantum information; in particular the optical detection of ultrasound for a new way of biomedical imaging.

Studying rare-earths for quantum information has been a very fertile area and has resulted my publishing nine journal articles in Physical Review Letters and two in Nature.
