1 Research

In my research I am motivated to increase survey quality and thus my work for international and national surveys and my research have always been tightly connected. Together with colleagues I was able to benefit greatly from the funding that we acquired over the years and I am grateful for the collaborations that have resulted in more than 50 publications and over 100 presentations.
