About

I am a former assistant-professor of mathematics at the Univ. of Amsterdam (1974-1986), with specialization in group theory and representation theory of groups. I worked more than 35 years for IBM, though not in research. Currently I am an executive professor at TIAS School for Business & Society in Utrecht, responsible for the Business Analytics and Artificial Intelligence track. My Erdös number is $3$. You can reach me at [email protected], or [email protected]
