This commitment includes providing intellectual support, finding necessary resources, and opening up opportunities for further growth. When cooperating with other (academic or industrial) partners I am committed to be a reliable and responsive partner expecting the necessary respect as I respect others for the values and goals they stand for. Furthermore, I am committed to challenge continuously my assistants and students in their work with the ultimate goal to perform outstanding research leading to outstanding results. I strongly believe that only active participation in the research community by publishing research results and ideas provides the stimulating working environment necessary for excellent research.
