Dr. Christian Westheide

I am a Senior Lecturer in Business Administration with special focus on Financee at the Stockholm Business School, Stockholm University. I am also a Research Affiliate of the Leibniz Institute for Financial Research SAFE. My primary research focus is empirical financial market microstructure, with particular emphasis on European equity markets. In other research, I explore the interactions between institutional investors and firms and banks. Additionally, I contribute to meta-science studies.
