The Bul­gar­i­an Acad­e­my of Sci­ences (BAS) is the lead­ing sci­en­tif­ic cen­ter in Bul­gar­ia that con­ducts sci­en­tif­ic research in accor­dance with uni­ver­sal val­ues, nation­al tra­di­tions, and inter­ests. The BAS par­tic­i­pates in the devel­op­ment of sci­ence world­wide by con­duct­ing research, train­ing, and activ­i­ties of nation­al and inter­na­tion­al impor­tance and solves prob­lems relat­ed to the sci­en­tif­ic devel­op­ment of Bul­gar­ia. The BAS is autonomous and con­sists of a Soci­ety of Aca­d­e­mi­cians, Cor­re­spon­dent Mem­bers, and For­eign Mem­bers. It pub­lish­es and cir­cu­lates dif­fer­ent sci­en­tif­ic works, ency­clo­pe­dias, dic­tio­nar­ies and jour­nals, and runs its own pub­lish­ing house. The Acad­e­my has a pol­i­cy for the devel­op­ment of sci­ence and inno­va­tion as a con­di­tion for eco­nom­ic progress in the coun­try and is an active par­tic­i­pant in the Euro­pean Research Area (ERA). Today, the BAS com­pris­es 42 autonomous sci­en­tif­ic units and is an orga­ni­za­tion gov­erned in accor­dance with demo­c­ra­t­ic prin­ci­ples. The Acad­e­my employs about 3,000 sci­en­tists, account­ing for about 15% of those engaged with sci­ence in Bul­gar­ia. The BAS pro­duces about half of the sci­en­tif­ic out­put in the country.
