Prof. Stang conducts epidemiological field studies as well as various data analysis projects in the field of oncological and cardiovascular diseases. In addition to this research content, he has always published methodological work for epidemiology and biometrics. He has long been concerned with the problems of null hypothesis significance testing, a hybrid of two different statistical schools of thought (Fisher’s significance testing and Neyman & Pearson’s null hypothesis testing) that are incompatible with each other.

This interest was sparked by his two mentors, Kenneth J. Rothman (Boston, USA) and Charles Poole (now Chapel Hill, USA), with whom he has been working since 1995.
