With a background in dance, improvisation and vocal performance my artistic focus has the past 20 years been increasingly on computer music. The work in computer music has developed alongside a study of pure mathematics. Especially algebra, group theory, number theory and geometry in a wider sense have been important. The work in spatial audio has been a natural extension of my interests in geometrical transformations. Lived in Amsterdam, NL, for several decades but I am now based in my country of origin, Denmark.
