- The Kilo Degree Survey (KIDS)
- KIDS is a 1500 square degree public imaging survey in the Sloan colors (u',g',r',i',z') with patches in both the Northern and Southern skies. The survey will use the OmegaCAM instrument mounted on the VST (VLT Survey Telescope). It is expected to start mid-2011.
- A parallel survey called VIKING (VISTA Kilo-degree INfrared Galaxy survey) has started mid-2010 on the VISTA telescope on Cerro Paranal. It complements the 1500 square degrees of the VST-KIDS survey in the 5 broadband filters Z,Y,J,H,Ks. Combined with KIDS, this will yield a unique 9-band optical-IR survey with depth approximately 2 mag deeper than Sloan and 1.4 mag deeper than UKIDSS-LAS.

- VESUVIO (VST/OmegaCAM Exploration of SUperclusters Voids and Intermediate Objects)
The VESUVIO project is a multi-band, wide-field survey of nearby superclusters of galaxies. Main scientific goals of the survey are the study of the properties of the galaxy population in the whole range of environments, from cluster cores to voids, and to study the transformations of these properties in relation to the local density and to the properties of the diffuse medium, both inter- and intra-cluster hot (X rays) and cold (HI) gas components. The project aims to study the transitional regions in between the dense clusters and the voids. In these regions we plan to map structural and morphological transitions and transformations in the properties of stellar populations. These processes relate to the hot inter- and intra-cluster medium and affect the cool gas component within these galaxies.

- Astronomical Wide-Imaging System for Europe (Astrowise) Web Page
Since 2003, I am envolved in the development and testing of Astrowise which is a system for data reduction and data mining of the large amount of data which will be produced by the OmegaCAM camera at the VLT Survey Telescope (VST) and other wide-field cameras.

- German Astronomical Virtual Observatory
I am part of GAVO, the German Astronomical Virtual Observatory. GAVO is a project, sponsored by the BMBF, for building a "Virtual Observatory" platform to support modern astronomical research in Germany. It is the German contribution to the international activities aiming at the creation of a global Virtual Observatory (VO) network. The GAVO project team aims at providing fast and easy access to astronomical data archives and related documentation, as well as a capability to use sophisticated software tools for new studies.
