Industrial applications and collaborations

Developed methods, models and analysis tools are applied to industrial processes and problems, e.g.:

In November 2012, I obtained a certificate for university-level didactics, teaching, and project management. The certificate was obtained from the Martin-Luther-University Halle and it required about 160 hours of intensive training covering topics like general and university-level teaching and didactics, various teaching and learning scenarios, specific subjects such as colleague and student advice, as well as project management and negotiations.
