With view to the specific features of its subject matters, NAIM-BAS consists of the following structural units: five chronological and subject departments (Department of Prehistoric Archaeology, Department of Thracian Archaeology, Department of Classic Archaeology, Department of Medieval Archaeology, Department of Numismatics and Epigraphy), a Problematic Group (Department for Interdisciplinary Research), two Branches for excavations at the Old Bulgarian capitals (in Shumen and Veliko Tarnovo) and a Museum of Archaeology. The structure of the Museum of Archaeology was changed in 2003 in order to improve its efficacy: two departments – Exhibitions and Depositories – were set up. The research, administrative, economic and financial issues at NAIM-BAS are serviced by several service units (Editorial Group, Archives, Accountant’s Office, Secretariat). Dr. Lyudmil Vagalinski, Associate Professor, is Director of the NAIM-BAS, Dr. Hristo Popov, Associate Professor, and Dr. Maria Reho, Associate Professor, are Vice-Directors, and Dr. Andrey Aladzhov, Chief Assisstant, is acting Scientific Secretary.
Currently, the academic staff of NAIM-BAS consists of 67 people: 8 Doctors of Science, 59 PhD, 7 Senior Research Associates 1st degree, 38 Senior Research Associates 2nd degree, 13 Research Associates 1st degree, 6 Research Associates 2nd degree, 2 Research Associates 3rd degree.
Various activities of NAIM-BAS are performed in close collaboration and interaction with the museums in the country, state institutions (Ministry of Culture, Ministry of Education and Science, National Institute of Cultural Monuments), regional and local executive authorities and various nongovernmental organizations.
