My current research focuses on issues in branding (e.g., how brand extensions work), distribution channels (e.g., multi-brand versus single-brand retailing), consumer search (how marketing strategies respond to consumer search costs), and advertising (exogenous versus endogenous targeting). In previous work I have studied market segmentation, product differentiation, and money-back guarantees. I currently teach Marketing Strategy to MBA students, and Marketing Theory and Advanced Topics in Marketing Strategy to Ph.D. students.
