Sebastian was born in Manchester, England, and grew up in Switzerland before moving to London at the age of 21, where he creates across platforms in theatre, film, print, and online, as a writer, director, and occasionally performer.

He is the author of several stage plays, ranging from contemporary relationship drama (The Power of Love) and the topical examination of religious fervour (Elder Latimer is in Love), to the 'apocalyptic comedy' Top Story, and a celebration of Shakespeare's poetry in The Sonneteer.

His short films and debut feature The Hour of Living have been screened at festivals worldwide, and he is the author of the experimental online project EDEN by FREI - 'a concept narrative in the here & now about the where, the wherefore and forever', from which the EDEN miniatures series has been released in paperback and as ebooks, and from which his 'picture story book for grownups', The Snowflake Collector, has also been published in hardback and as ebook, illustrated by Diego Cassia.

Sebastian is a contributing author to A Quantum City (Eds. Hovestadt/Bühlmann, Birkhäuser, 2015) with Orlando in the Cities, a playful literary odyssey through 2500 years of civilisation, and co-author, with Ludger Hovestadt and Vera Bühlmann, of A Genius Planet (Birkhäuser 2017).

Sebastian lives in London and works wherever his projects take him. He is also guest lecturer at the Department for Architecture Theory and the Philosophy of Technics at the University of Technology Vienna (TU Wien).

Angel is his first novel.
