I am Co-PI of The ALMA Spectroscopic Survey (together with Drs. Chris Carilli, Manuel Aravena, and Roberto Decarli) in the Hubble Ultra Deep Field (ASPECS), a 3D survey of gas and dust in distant galaxies. It focuses on the best-studied cosmological deep field, the iconic Hubble Ultra Deep Field.
I am Co-PI (together with Prof. Ian Smail and Dr. Axel Weiss) of the LABOCA ECDFS Submm Survey (LESS), an extragalactic submillimetre survey using the LABOCA Camera on the 12m APEX Telescope. This large program has been the basis for extensive ALMA follow-up (ALESS).
I was the PI of the high-z quasar search using the Pan-STARRS1 telescope. This survey has led to the discovery of more than a hundred quasars at redshifts > 6, less than 1 Gyr after the Big Bang. This survey was the foundation of numerous multi-wavelength follow-up studies, from the X-rays to the radio regime.
I am Co-I on LADUMA, which will be the deepest neutral hydrogen survey to date. It will use more than 2000 hours to observe a single pointing encompassing the Extended Chandra Deep Field South (ECDF-S) with the aim to observe neutral hydrogen in galaxies out to redshifts z=1.
