[2] Upon graduation he founded his own ensemble SENSEDANCE and continued to dance with other choreographers, namely Duncan Macfarland, Murray Louis and most importantly Alwin Nikolais.
His interest in early modern dance led to guest appearances with repertory companies in the works of Isadora Duncan, Doris Humphrey and Anna Sokolow.
In addition to Moon, he has collaborated with numerous composers and musicians, including Ricardo Llorca and Leslie Wildman as well as designers of different disciplines, e.g. Fabio Toblini.
A program featuring duets (2013) showcased Rübsam's ability to portray different kind of relationships by using a wide variety of original movement vocabulary both in ballet and modern/contemporary dance idioms.
The lively Sarao with music by Ricardo Llorca paired Erin Ginn with Matt Van, who also appeared with Juan Rodriguez in the male duet Russian Lesson.
Heidi Green and Oisin Monaghan floated through the movement poem An einsamer Quelle to Richard Strauss, while the reflective and sculptural Borders (to spoken word) featured Temple Kemezis with Rübsam.
Among his well-known disciples and guest dancers are Violetta Klimczewska, Ramon Thielen, Andrea Long, Carlos Molina, Dartanion Reed, Christine Reisner, as well as Samuel Lee Roberts and Akua Noni Parker, both with Alvin Ailey American Dance Theater.
Rübsam produces select events ranging from a tribute to theater critic Eric Bentley at New York City's Town Hall with Tony Kushner, Karyn Levitt, Austin Pendleton, Michael Riedel, and Glen Roven to "RADICAL BODIES: Anna Halprin, Simone Forti, Yvonne Rainer" at Hunter College's Kaye Playhouse and the Beverly Blossom Festival at the 92Y in which he performed alongside Tandy Beal, Betsy Fisher, Debra Noble, and others.
