In connection with the theories of Johann Gottlieb Fichte, Nicolai Hartmann, Max Scheler, Manfred Eigen, Erich Jantsch and others he wrote his thesis to the topic "The Human Being in the evolutionary layers of self-organization."

In 1993, together with his friends and with the support of the Saxon Prime Minister Kurt Biedenkopf, he founded the socio-ecological model project LebensGut in Pommritz.

He received the degree of Doctor habil of Social Ecology 1999 at the Humboldt-University of Berlin, with reviews from Rupert Riedl and Vittorie Hösle.

In a project sponsored by the German Federal Ministry of Education and Research,[5] Hosang together with the environmental scientist Bernd Markert and the biochemist Stefan Fränzle compared various socio-ecological thinking and research approaches and developed the theory of the biocultural or "emotional matrix"[6] – an emotional depth structure which, according to her opinion, is the basis of all human cultures and societies and which has a similar meaning to social systems as the genetic code for biotic systems.

Together with the neurobiologist Gerald Hüther and the theologian Anselm Grün, Hosang developed an inter- and transdisciplinary theory of love and creativity.
