Notably, Grobys is the only senior researcher at the University of Vaasa to have been granted two docentships—a distinction that reflects a uniquely high level of academic qualification within the institution.
At the University of Vaasa, he also became the first senior researcher to supervise a doctoral student under a co-tutelle agreement in collaboration with the University of Turin, marking another important institutional milestone.
For the academic summer term of 2025, Grobys has been appointed Guest Professor at the Christian-Albrechts University (CAU) of Kiel, Germany, where he holds full responsibility for both teaching and research in the Department of Monetary Economics and International Finance.
In addition to his academic achievements, Grobys brings several years of experience from the financial industry. As a Risk Analyst at Klarna AB, he led various projects related to merchant credit risk control.
His research is published in prestigious international finance journals, with approximately 75% of his scientific output appearing in A-ranked outlets. His work has received widespread media attention, having been featured in The New York Times, Forbes, AlphaArchitect, and Cointelegraph, among others.

Books
"Rationality: The Antidote To Being Fooled By The Industry".
(ISBN-13: 9789528066743)
About this book: Inspired by Nassim N. Taleb's works The Black Swan, Antifragile, and Skin in the Game, Klaus Grobys explores how rationality and irrationality are manifested in human behavior across various domains of human life. The stories discussed in this book are based on real-life observations. This work deals with political incorrectness, the presence of concentration in virtually all domains of human life, the carelessness of industries manifested in profit-maximizing at the expense of simple folks, and various other issues that many authors typically avoid. The objective of this book is first to acquaint the reader with a new perspective concerning the concept of rationality and second to equip the reader to identify traps set up by profit-maximizing industries and self-serving lobbies.
