After receiving his Classical Harmony, Fugue, and Counterpoint degrees with honours, Kostis began studying contemporary composition, supervised by the composer Stathis Oulkeroglou in Athens. He became familiar with the 12-note system, and composed several solo pieces for flute & piano. In 2009 he was offered a place in the Masters course in Film & TV composition at the University of Bristol. Under the supervision of William Goodchild and Martin Kiszko he completed his Masters with distinction, studying Film Analysis, Media Composition, Electronic/Studio Composition, Orchestration and Instrumentation, along with Advanced Acoustic Composing Techniques taught by one of the leading contemporary composers in Europe, John Pickard. After successfully completing his Master’s degree, Kostis was accepted as a PhD candidate in Acoustic Composition at the University of Bristol, under the supervision of Neal Farwell. During his masters and PhD years Kostis has been commissioned to compose for over 20 films, promotion videos, documentaries and computer games.
As a concert-music composer, Kostis has completed many solo and ensemble works, including String Quartets, Full Orchestral Pieces and smaller scale works.
Recently he finished a new piece for chamber orchestra, under the supervision of Bruce Broughton, an established American film composer known from many films scores in Hollywood.
