Around 50 participants attended the workshop while Wiener Lab researchers Sherry Fox, Maria Liston, Vicky Elefanti, Sireen El Zaatari, Tatiana Theodoropoulou, Rozalia Christidou and Eleni Nodarou showed off their work.

Members from the Ephorate of Paleoanthropology and Speleology of Southern Greece and Harokopio University also participated, as did University of Athens professors Yiannis Papadatos, who helped advertise the event. Rounding out the attendees were Georgia Kourtessi-Philippaki, who attended the workshop with students and members of the German Institute at Athens, and members of the American Foundation for Bulgaria.
