Professor Loos studies behavioral and household finance with a particular focus on financial advice, (digital) product innovations like ETFs, fintech and individual investor behavior in general. To address new fundamental questions his research is mostly based on big proprietary datasets stemming from collaborations with banks and fintechs as well as from field- and laboratory experiments.

Before joining TUM School of Management in June 2020, Professor Loos held positions as Associate Professor at the University of Technology Sydney, and as Assistant Professor at Mannheim Business School and Goethe University Frankfurt. He completed his PhD in 2015 at Goethe University Frankfurt with his thesis titled “Potential Solutions to Individual Investors’ Investment Mistakes”.
