I am a behavioral economist specializing in ecological economics, subjective well-being ("happiness") research as well as innovation research. The focus of my work is on empirical economic research. Recently, I have been most interested in the following areas of this field: (1) Implications of identity on human behavior (e.g. in the form of green identity or "artificial group identity"), (2) the extent to which occupational identity is conducive to worker well-being and (3) the relationship between self-employment/ entrepreneurship and well-being.
