The RECETOX Research infrastructure has been dynamically developing in the last years, both in terms of services and capacities, which required major organization changes. Until the end of 2020, the RECETOX RI was formaly organized in three basic core facilities – CELSPAC Population Studies,Trace Analytical Laboratories and IT Services. The internal organization was informal and was not described in formal documents nor in the internal information systems. In 2021, the organization of RECETOX RI was changed and every core facility was divided in several organizational units. The RECETOX RI has been managed by its director Jana Klánová assited by the RI manager Petra Růžičková. The current organizational structure of the RECETOX RI is shown in chart.
