Much of the history of star and galaxy formation in the universe is hidden by dust. My research is concerned with using long wavelength observations, in the mid- to far-IR and submillimetre, to see through the obscuring dust and to uncover the role and internal physics of dusty objects in the history of the universe. As part of this work I am involved with a wide range of observational programmes. These include:
- The Planck Surveyor
This is an ESA mission to survey the entire sky at submm and short radio wavelengths. Its main goal is to better understand the cos,mic microwave background, but it will also produce an all-sky survey of far-IR and submm luminous objects in the local and distant universe. This will give us unique new insights into dusty galaxies and the processes that drive them. You can read more about the day-to-day work on Planck at planckmission.wordpress.com
- The Herschel Observatory
This is an ESA space observatory that will operate in the far-Infrared. As an observatory, it is a general purpose telescope. My main interest is in the study of distant galaxies with Herschel, and I am involved with several large scale surveys that will be undertaken with Herschel. These include the HerMES project, the largest single programme on Herschel, aimed at distant dusty galaxies at earlier stages of the universe, and the H-ATLAS project, the largest area survey to be conducted with Herschel and aimed at determining the properties of dusty galaxies in the local universe and uncovering the properties of rare and unusual dusty objects.

SPICA is a proposed Japanese infrared space observatory. It will be the successor to Herschel and, since it will have a large cooled primary, it will provide a massive boost in sensitivity compared to Herschel. I am part of a team putting together a proposal for a Spectrometer instrument for SPICA, base din part on our work with the SPIRE instrument for Herschel. SPICA has now been selected as a new mission for the European Space Agency and development for it, negotiations with our Japanese colleagues, and work on the European SPICA instrument called SAFARI, are now moving to the next stage.
SCUBA2 is the next generation of ground-based submm instruments. It will operate at the JCMT and will represent a factor of 1000 increase in capability over the previous generatioon of submm cameras. I am involved in a number of extragalactic survey progarmmes with SCUBA2, including the deep extragalactic survey, and the SASSy all sky survey. I am also involved with observations using SCUBA, including a significant role in the SHADES large area SCUBA survey.
Spitzer is NASA's infrared space telescope, and is currently operating. I am part of the SWIRE legacy team which has conducted the largest area survey with Spitzer, and am invovled in a number of other observational programmes.
