My research interests focus on the analysis of customer relationships, with special attention towards the adoption and acceptance of eco-innovations. I complement my theoretical work with empirical studies using qualitative and quantitative research designs. Noteworthily, I am using structural equation modeling (SEM), in partiuclar partial least squares (PLS) path-modeling and/or experimental designs with neuroscience tools to answer my research questions.
