In her work, she explores somatic practices and philosophical questions, which she uses as a starting point for her artistic investigations into the perception of one’s own body, the environment, and societal challenges.

Exploring movement and the decision-making mechanisms underlying it often marks the beginning of a process. Through her movement language, she constantly re-examines the architecture of the body. Her engagement with space and time gives rise to recurring questions, often influenced by philosophy or the visual arts. Her pieces are both choreographed and improvised or site-specific. Susanne Mueller Nelson regularly collaborates with artists from other disciplines.

Following her athletic career on the national rhythmic gymnastics team, Susanne Mueller Nelson turned her attention to the artistic side of movement in 1984, first completing her dance training in Montpellier. There she also encountered the work of Rui Horta and Dominique Bagouet. These two very different approaches, as well as the subsequent four-year stay in New York (made possible by a scholarship from the Otto Tschumi Foundation), shaped her subsequent work: on the one hand, the abstract yet precise handling of movement; on the other, the exploration of movement to its physical limits and the engagement with space, presence, and the relationship with the audience. Since completing her training as a Feldenkrais® teacher (2001–2005), this method has formed an important foundation for these very questions and her artistic practice.

Under the name co.ainsi.danse, she has produced numerous full-length and several shorter pieces to date, which have been presented in Switzerland and abroad. In addition, she is a sought-after guest teacher both domestically and internationally.

In 2010, she received the OFF Stage Fellowship from the Canton of Bern, which enabled her to give her artistic work a new direction. In 2013, she completed the MAS TanzKultur program at the University of Bern. She further developed the theme of the mediation of contemporary dance performances, which formed the basis of her thesis, and began to put it into practice. Since then, she has been a sought-after expert in the field of arts education.

From August 2016 to January 2017, she was in Berlin on a studio residency grant from the Canton of Bern and in 2020 she received the Continuer scholarschip oft he Canton Bern.
