The Rhea Study has been running since 2006, however we are always positive to new collaborations and ideas from interested experienced and/or young researchers.

Data from the Rhea study has been used in international and European collaborations over the years to study various scientific fields such as epidemiology, nutrition, child obesity, etc.The study evolves as the years pass and the rich data give many opportunities for research and new ideas to be developed.

Interested researchers can contact one of the Rhea Principal Investigators, Dr Leda Chatzi ( and Dr Manolis Kogevinas (, with their questions or proposals.

Alternatively, investigators interested in collaborating with Rhea or in using data, may complete the Collaborator's Request Form. The Rhea group reviews proposals and requests on a monthly basis and will respond as soon as possible.
