The Scientific Council of the Polish Centre of Mediterranean Archaeology of the University of Warsaw approved the changes at the helm of two PCMA UW expeditions in Egypt: in Berenike and Naqlun.
Dr. Mariusz Gwiazda (Faculty of Archeology, University of Warsaw) took over co-directing the Berenike Project on behalf of the PCMA UW. He replaced in this role Iwona Zych, who was the head of the Polish leg of the Polish–American expedition since 2008. The American partner of the project was University of Delaware, with Prof. Steven S. Sidebotham as the director. Dr. Gwiazda participated in the project as a specialist in material culture. As field director, he took part in other PCMA UW projects in Egypt (Marea Archaeological Project) and in Lebanon (the Polish-Lebanese Archaeological Expedition in Jiyeh/Porphyreon), where he also directed a project in Khan Khalde.
The management of the expedition in Naqlun was entrusted to Dr. Robert Mahler (PCMA UW). The previous head of the expedition, Prof. Włodzimierz Godlewski held this position since 1986. The fieldwork in Naqlun was carried out between 1986 and 2016. Dr. Robert Mahler specializes in bioarchaeology. He participated in the works of the expedition in Naqlun, and cooperates with other PCMA UW projects in Egypt (Alexandria), and Sudan (Dongola and El-Zuma).
