History Tares GmbH

1999: Targeted Research (TaRes) was founded 1999 as a start-up out of the University of Hamburg. TaRes conducted research in all areas of the agricultural sector for private and public research institutes and companies in the field of genetic engineering and biotechnology.

From 2018 on Prof. Wilhelm Schaefer will serve as an mentor for PhD studies.
Between 1999 and 2014 four PhD theses, 8 patents and 5 publications in international peer reviewed journals emerged out of the collaboration with various companies (BASF, KWS).
