Our group is currently involved in a number of international research projects and collaborations, including
- The Parkes High Time Resolution Universe Survey, which will map the entire sky at sub-millisecond timescales in the search for pulsars and extragalactic radio bursts.
- High-Precision Pulsar Timing at Parkes, the longest-running pulsar timing programme at the Parkes Observatory and a primary contributor to the Parkes Pulsar Timing Array search for the cosmological gravitational wave background.
- The Giant Metre Wave Telescope (GMRT) software backend project: to search for pulsars and extragalactic bursts at the GMRT and perform coherent dedispersion of radio pulses.
We have conducted large-scale surveys of intermediate to high galactic latitudes for millisecond pulsars and discovered many interesting objects, including PSR J1909-3744, a millisecond pulsar with a very small duty cycle that has the most accurately determined millisecond pulsar mass. Since 2001, our group has held the record for the highest precision pulsar timing, work that has enabled new tests of general relativity and placed the best limits on the stochastic background of gravitational waves.
