Seven members of the Laboratory of Model Invertebrate Organisms stand next to each other outside the building of the Institute of Bioorganic Chemistry of the Polish Academy of Sciences in Poznań. The group poses on a gravel path in front of a modern building with large windows, surrounded by green shrubs and trees. The women are dressed in casual, semi-formal clothing and are looking toward the camera.
