Your main research interests lie in starburst galaxies.
From your base, high on a rocky crag overlooking the capital of Scotland, you have long been studying starburst galaxies in the local universe. Perhaps it is the howling wind and lack of insulation in your offices that does it, but the glowing warmth of a galaxy violently forming vast numbers of stars has a great attraction to you.
Over the last few years, you have watched with incredulity as group after group has claimed to detect new-born galaxies in the rest-frame UV! If there is one thing you learn from low redshift galaxies, it is that star formation always takes place accompanied by dust. And dust is really extremely good at blocking UV light. In our own galaxy, star formation takes place in giant molecular clouds, and you won't get very far studying them in the UV. All the nearby galaxies that are forming stars at reasonable rates are very dusty: most of the radiation from their young stars and supernovae is absorbed by dust and re-radiated in the far-IR.
So it is no wonder to you that the Caltech mafia and their friends are only finding wee little galaxies forming stars at some pathetically gentle rate. Any decent, strapping starbursts will be so dusty that the little dears won't see a thing with their fancy UV Lyman-limit techniques. There could be any number of new-born galaxies in the early universe, forming stars at enormous rates, and the Ly-limit people would never know.
How do you find and study starbursts in the local universe? You look in the far-IR, where these galaxies stand out like sore thumbs (they are called ultra-luminous IRAS galaxies for a reason, you know). Another possibility is to use mm-wave telescopes to look for molecular emission from these galaxies.
You have just finished building a new instrument, called SCUBA (Sub-mm ContinUum Bolometer Array), which goes on the 15-m James Clerke Maxwell Telescope (JCMT) that you run on Mauna Kea. With this, you could, in principle, detect redshifted far-IR thermal radiation from dusty high-z galaxies. And this is just what you are finding: many galaxies, which are almost certainly at high redshifts, with enormous amounts of hot dust. These things must be forming stars at colossal rates: far more actively than those pathetic Ly-limit galaxies. Clearly everyone has been looking in the wrong wavelengths to find new-born galaxies.
