Jonathan came to contact improvisation in 2013, after twenty years of training in aikido, a martial art that can be said to be a direct ancestor of this dance form. His movement and teaching styles are deeply informed by his experience with the Feldenkrais method of somatic education, as well as by a daily meditation practice in the Tibetian Buddhist tradition. In addition to thousands of hours of experience teaching aikido, he has taught workshops or classes in contact improvisation at a half-dozen locations in the US and Canada. In his day job, he studies ocean physics.
