I develop methods to study how consumers categorize products and brands. Specifically, I am interested in understanding how consumer intuitively see some objects (e.g., products, brands) as similar in some way, and the consequences of those judgments. My research in this area relates to card sorting, unsupervised learning methods (e.g., clustering) and classification.
