Dag spent 15 years of his career in the Capgemini Group, where he held several positions in the Nordic region as well as globally. From 2002 to 2005, he headed the global telecom and media consulting practice. Through his consulting career, he worked with major clients in the massive transition from the analogue media world to the digital connectivity of the new millennium. A hallmark of this practice was to build an unbeatable team, based on deep industry expertise combined with exquisite people skills. Following his music education, Dag has conducted several choirs, presenting innovative musical projects. From 2019, he teaches choral leadership at the Academy of Music and Drama, University of Gothenburg.
The various threads in the professional weaving led to the appointment as associate professor in arts management at Oslo Business School - Oslo Metropolitan University in 2015. His key responsibility is a curriculum serving artists and culture workers who seek to expand their managerial competence. He teaches leadership courses at several universities.
Dag's research interests fall within the ambiguous label 'musical leadership', encompassing the music domain as well as the muse within every type of leader. In much of the research, the musical moment is used as a horn of plenty to shed light on a number of organisational issues. Aesthetics and phenomenology is often the favoured approach to understanding what goes on in leadership processes.
