Academic Research

My research explores how consumers and managers make judgments and decisions, with a particular focus on their intuitions about data, metrics, and statistics.

I have published in leading journals across marketing, management, and psychology, including the Journal of Consumer Research, Journal of Marketing Research, Management Science, and Journal of Experimental Psychology: General.

I have also presented my work at academic institutions throughout Europe, North America, and Asia, including INSEAD, London Business School, Wharton, Stanford, New York University, the Hong Kong University of Science and Technology, and the National University of Singapore.

Currently, I serve as an Associate Editor at the Journal of Consumer Research and sit on the Editorial Review Board at the Journal of Marketing.

Leveraging Digital Advertising Platforms for Consumer Research.

Journal of Consumer Research. With Michael Braun, Stefano Puntoni and Eric Schwartz.

Digital advertising platforms have emerged as a widely utilized data source in consumer research, yet the interpretation of such data remains a source of confusion for many researchers. This paper aims to address this issue by offering a comprehensive and accessible review of four prominent data collection methods proposed in the marketing literature: “informal studies,” “multiple-ad studies without holdout,” “single-ad studies with holdout,” and “multiple-ad studies with holdout.” By outlining the strengths and limitations of each method, we aim to enhance understanding regarding the inferences that can and cannot be drawn from the collected data. Furthermore, we present seven recommendations to effectively leverage these tools for programmatic consumer research. These recommendations provide guidance on how to use these tools to obtain causal and non-causal evidence for the effects of marketing interventions, and the associated psychological processes, in a digital environment regulated by targeting algorithms. We also give recommendations for how to describe the testing tools and the data they generate, and urge platforms to be more transparent on how these tools work.
