Stefan Dodounekov, president of the Bulgarian Academy of Sciences (BAS), died after a brief illness on August 5, aged 67, the academy said in a statement on August 6.
Reports in Bulgarian media said that Dodounekov, elected president of BAS in June, suffered a stroke.
Dodounekov, who received his Ph.D in mathematics in 1986 and became a full member of the academy in 2008, was elected president on a promise of avoiding drastic change in the way the BAS is run, but also opening up the academy to the public.
He was previously head of the BAS Mathematics Institute and a professor at Kliment Ohridski Sofia University. He has authored 12 mathematics textbooks for pupils.
A book of condolences will be opened in the grand foyer of the BAS building on Tsar Osvoboditel Boulevard, next to Parliament, on August 7, after 9am. Dodounekov will be buried in his native town of Kilifarevo on August 9.
