Research interests

Coordinating the Target project  (chair steering committee Target Fieldlab) and leading OmegaCEN a National datacenter for wide field astronomical imaging, funded by the Netherlands Research School for Astronomy NOVA.

OmegaCEN is building and supporting advanced Survey Information Systems. At the center, ~17 staff and PhDs are involved in research and development of data basing and processing of very large data sets. Founder of OmegaCEN (2002), Astro-WISE (2001), Target (2008), Target Holding bv (2009), Intrinfo (2009),  Infoversum Foundation ( 2012),  now DOTliveplanetarium(2017)
