Born in Hamburg, Kochheim began playing the piano at the age of 7. As a teenager he attended productions of Peter Zadek, which aroused his interest in theatre. He studied art history in Munich, with the minor subjects Neue Deutsche Literatur [de] and theatre studies. In the season 1992/93 he attended a performance of Verdi's Un ballo in maschera and afterwards turned his attention increasingly to music theatre. During an internship at the Staatstheater Augsburg he got to know John Dew and accompanied him occasionally as an assistant at the Vienna State Opera. In 1995 Kochheim finished his studies with a Master of Arts and worked for five years as Dew's assistant at the Theater Dortmund.[3]
Since 1 May 2017, Kochheim has been director of Den Jyske Opera (Dänische Nationaloper Aarhus).
On 24 January 2018 accusations of "sexualised abuse of power" were made against Kochheim, who had previously rehearsed his musical production Ragtime at the Graz Opera. He had, already as opera director at Staatstheater Braunschweig,[9] contacted several actresses via Facebook, sexually harassed them and thereby abused his position as director.[10][11][12][13]
Kochheim's own plays include "C.Q.D". (premiere in Dortmund, 1998) and Tschaikowsky (premiere in Wilhelmshaven 2002). He also wrote the libretto for the opera Kniefall von Warschau named after Willy Brandt's genuflexion in Warsaw on 7 December 1970, (music Gerhard Rosenfeld), which premiered in 1997 in Dortmund under the direction of Dew.[2][3]
