His research interests encompass the broad discipline of frequency metrology, precision and quantum measurements and low temperature, condensed matter and quantum physics. Over his career he has developed a variety of precision and quantum measurement tools in his laboratory allowing the investigation of many areas of Physics and Engineering. In particular he is interested in developing new precision technologies to undertaking precise tests of fundamental physics and has also adapted such technology to the commercial sector. In the area of fundamental physics his work includes low energy precision searches for dark matter, Lorentz invariance violations and searches for high frequency gravitational waves. He also leads the ORGAN axion Dark Matter detector collaboration co-funded by both Centres. Also, in 2019 his group become an official collaborator of the Axion Dark Matter eXperiment (ADMX) situated at the University of Washington.
