Ros is a Russia-born British-German film composer, music producer, conductor and musician. His musical training began at the age of five when he was admitted at the prestigious Gnessin School of Music for the musically gifted as a violinist in Moscow, Russia. During his teenage years Ros continued his studies at the University of Music in Munich, Germany as well as the David Oistrakh-Academy. During that time, Ros won multiple awards as a violinist and performed as a soloist with orchestras like the Georgian Chamber Orchestra, chaired by star-violinist Liana Issakadze. Ros later went on to study at the world-famous University of Music and Performing Arts, Vienna, where he was taught by a number of internationally acclaimed violinists including Dora Schwarzberg, Herman Krebbers, Roman Nodel, and Alexander Arenkow. With his piano trio and the Fidelio-Quartet, Ros performed across three continents, as well as on national TV and national radio. With this ensemble he studied with outstanding musicians like maestro Mstislav Rostropovich, the Amadeus-Quartet, and the Janacek-Quartet. Ros also became second leader of the European Philharmonic Orchestra, performed at renown venues such as the Musikverein Vienna and worked with noted conductors such as Yakov Kreizberg.

Due to a sudden hand injury Ros was forced to give up his promising violin career and thus changed his professional focus from concert violin to composition and conducting. Ros went on to study Classical Composition, Composition for Screen and Jazz Composition at the University of Music and Performing Arts, Vienna and the Royal College of Music London. His composition teachers include Israeli composer (and Walter Bigelow Rosen Professor of Music at Harvard University) Chaya Czernowin, British electroacoustic composer Michael Oliva and Austrian Jazz composer Christian Mühlbacher. Ros's conducting teachers include Uroš Lajovic (principal conductor of the Slovenian Philharmonic), Dane Lam (principal conductor of China's Xi'an Symphony Orchestra) and Jean-Bernard Matter (former assistant to maestro Pierre Boulez). Ros’ music was premiered at renowned venues, such as the Konzerthaus Vienna, and as a conductor Ros has worked with the Macedonian Symphonic Orchestra, the Prague Metropolitan Orchestra, The Nouvelle Cuisine Big Band and various others.

Ros’ most recent composer credits include the HBO Asia Original series Folklore (season 2, episode “Grandma’s Kiss”), for which Ros also recorded all violin solos himself. Ros has also scored two prime-time TV documentaries (ARTE and France 5), worked on several TV show episodes (ORF’s Newton, G4’s Proving Ground), composed additional music for two theatrical feature films, a host of short films as well as adverts. Ros also produced the orchestrations for seven prime-time feature films (ZDF) as well as several TV show episodes (ARD).
For his work, Ros received various awards and nominations, such as the Audience Award for Best Music
at the "British Animation Film Festival” or the nomination for Best Original Score at the "International Samobor Film Music Festival” and has been selected for BAFTA’s emerging talent program BAFTA Crew for four consecutive years since 2017.

Ros' release First Sunlight has also received editorial support from Apple Music, being added to Apple Music's Taking a Nap playlist. Furthermore, Ros' releases have been repeatedly playlisted on national radio (BBC 4 Radio and BBC 3 Classic Radio) and received support from the press (BBC Music Magazine, Newsquest Times Series, Arts Professional).
