Prof. Barth started his work in Aachen at the end of 2000 and meanwhile manages research groups of >30 members exclusively funded by grants and composed of both Fraunhofer and university employees. During the last 15 years of work in the field of biotechnology he successfully applied for 35 funded projects, thus raised ~ 14.420.000 EURO, filed 18 different patents applications, and wrote more than 80 scientific articles.
