个人简介
The main focus of my current research is in the study of galaxy formation and evolution in the Epoch of Reionization; focusing on the discovery of high redshift galaxies and quasars powered by the accretion of matter onto supermassive black holes. I work on the discovery of quasars and active galaxies that host supermassive black holes, the determination of the space densities, star formation rates and how and when galaxies and quasars form. In the past I have worked on the experimental determination of the rate of gravitational deceleration of the Universe. This work resulted in the unexpected discovery that the expansion of the Universe is accelerating.
My research also includes developing experimental survey techniques for discovering new high redshift quasars and using quasars to probe the baryonic content of the Universe. My group has pioneered the use of high redshift quasars to determine the mass of neutral hydrogen in the high redshift Universe via intervening absorption lines imprinted on the spectra of background high redshift quasars. I have also pioneered the use of mm and submm microwave radiation to determine the star formation rate in quasar host galaxies.
