Jozef is a founding member of RootlessRoot.

He graduated from the Academy of Music and Theater of Bratislava, completing his PhD Thesis in 2002. From 2002 to 2005, Fruček was a member of Ultima Vez/Wim Vandekeybus, creating Blush (stage and film versions) and Sonic Boom. Later, from 2005 to 2006, he collaborated with the Royal Flemish Theater in Brussels (KVS) on his own work.

In 2006, Jozef and Linda Kapetanea formed RootlessRoot as a vehicle for their own productions, research and teaching. And together with Kapetanea, he is developing the research program of Fighting Monkey Practice—an applied methodology of martial arts in the education of dancers, actors and movement practitioners. They regularly give workshops at international festivals and in vocational schools.

From 2006 to 2011, Jozef was on the teaching faculty at the Athens State School for Dance. Since 2012, he is member of the teaching personnel of the University Ludwik Solski State Drama School of Krakow in Poland.
