I'm a Professor and Discovery Outstanding Researcher at the University of New South Wales, where I head the Exoplanetary Science at UNSW group, within the Australian Centre for Astrobiology, physically located within the School of Physics.


My group currently hosts two faculty, three post-doctoral researchers and four graduate students, working on projects ranging from the search for exoplanets orbiting Sun-like main sequence stars (the Anglo-Australian Planet Search), the search for exoplanets around evolved stars more massive than the Sun (Rob Wittenmyer's Pan-Pacific Planet Search), a high intensity search for terrestrial-mass planets orbiting the two components of the nearest star (alpha Cen A and B), direct imaging observations of already known long-period companions to Anglo-Australian Planet Search stars, follow-up of transit candidates from the HAT-South planet search, and hunting for planetary-mass methane dwarfs in nearby young star clusters.


We are also actively pursuing new technologies for searching for exoplanets - especially the use of image slicing fibre technologies for improving spectrograph performance, the use of astrophotonic technologies for removing spatial information from the entrance apertures of astronomical spectrographs, and breaking the current cost-paradigms for high-resolution spectrographs on large aperture telescopes.


We work closely with colleagues across the Australian Centre for Astrobiology to examine the impacts of our exoplanetary discoveries on the question of habitable environments outside the Solar System - especially with the members of Prof. Jeremy Bailey's Planetary Science group, here within the Astrophysics Department.

About my research work ....

I grew up in the south-western suburbs of Sydney, attending St Patrick's College, Strathfield before doing a Science degree in Physics at the University of Sydney.


In 1987 I moved to Pasadena, CA to do a PhD in astronomy at the California Institute of Technology. Although I did small research projects there in VLBI, single-dish and inteferometer mm observations of ultra-luminous infrared galaxies, and IRAS infrared photometry of Asymptotic Giant Branch stars in the LMC, I eventually settled on a PhD project hunting for brown dwarfs (working with Neill Reid and Jeremy Mould).


Sadly, I didn't actually find brown dwarfs in the survey I did for my thesis, but I had a lot of fun trying. We also learned a lot more about M-dwarfs than we had known up until then, and I learned a lot about wide-field imaging surveys, infrared and optical photometry and spectroscopy, and doing astrometry with CCDs.


In 1992, I moved countries again to take up a Fellowship at the European Southern Observatory Headquarters in Garching, Germany. I continued working on brown dwarfs and CCD astrometry there (and indeed have done so to this day).


In 1994, I moved back to Australia as a Research Astronomer at the Anglo-Australian Observatory. I stayed on at the AAO for just over 12 years - for the first half of it as an AAO support astronomer, and for the last half of it as Head of Astronomy (and so managed the support astronomers). While at the AAO I got progressively more and more involved in exoplanetary research, and that has become the largest focus of my work today.


More personally ....


I am a compulsive reader - mainly of history and science fiction. Though not so much of the latter these days - as I get older, finding new writers I like (and haven't already "read out") becomes harder and harder.


I listen to a lot of BBC Radio 4, ABC Radio National and (when I can find the time and a quiet environment) classical music.


Despite growing up in Sydney as a follower of rugby league (and the now defunct Western Suburbs), I have become am a rusted-on Sydney Swans supporter. I watch far too much AFL during the footy season.
