I am a graduate engineer in the field of Architectur and Master of Science in the field of urban planning. I am living in Hamburg, Germany and work independently as an urbanist und publicist. As such I conceptualised the international City Link congress „Cities, Culture & Sustainability“ (Hamburg, September 2014). In 2009 I co-founded the ZZZ (agency for temporary use in Bremen, Germany) and leerstandsmelder.de (open croudsourcing platform to share informations concerning vacant buildings). In 2012 I published the bilingual book „second hand spaces – recycling sites within urban transformations” with my colleagues from the ZZZ. In 2013 I have been elected to the Chairman of Supervisory Board of the Gängeviertel Cooperative and to the second Chairman of the Gängeviertel redevelopment council.
