Stefan Griesser
Owner and founder of Varietas, started in 2009.
Stefan grew up as the son of a farmer and a professional gardener and has been breeding plants for over 20 years.
He is an expert in special and marginalized crops as well as forest gardens and other permaculture practices.
By trade, he is an evolutionary and population biologist with experience in marker assisted plant breeding.
He started studying biology, went over to agronomy and finished in environmental sciences at the ETH in Zurich.
He did his bachelor thesis work on soft and hard species borders in wild tomatoes, crossing and breeding them.
A paper he contributed to in that line of work can be found here.
His master thesis investigated regenerative agricultural practices. To this end he mapped permaculture and its application all over Switzerland
and created a systematic classification of permaculture practises in an agrarian and garden context splitting permaculture into group work found
mostly in urban agriculture, planning, implementation, biodiversity, animal husbandry, water-, soil- and energy-use as well as the ethical approaches.
Stefan has a wide interest in breeding and agronomy and is happy to assist in any capacity, alone or with his team, as a consultant or service provider for your breedings projects in this regard too.
