Born in Basel, Switzerland, I studied at the University of Basel before training at the International Theatre School Jaques Lecoq in Paris, where I also attended its L.E.M (Laboratoire Etude de Movement)

In 1994 I moved to England and co-founded Hoipolloi Theatre with Shon Dale-Jones. I designed and performed in most of the company's productions, touring throughout the UK and Europe, as well as the USA, Canada, Australia, Columbia and the Philippines. 

Hoipolloi's last ensemble-large-scale show that toured nationally was The Doubtful Guest which was co-produced with Theatre Royal, Plymouth for their main stage. 

I have also designed and co-directed Hoipolloi's award-winning collaborations with Hugh Hughes: Floating, Story of a Rabbit, 360, Stories From an Invisible Town and Things I forgot that I Remembered (a collaboration with the National Theatre of Wales).

I also directed his Carrie-Anne story which was recorded for BBC Radio4. Currently we are working on his next production 'The Ladder' which will open mid May as part of the North & Norfolk Festival
