choice modeling and conjoint analysis, and in segmentation analyses. In over 6 years each at Total Research Corporation and Opinion Research Corporation, he focused on multivariate methodologies in marketing research while serving in project direction, sales and data processing roles. Dave conducted his first discrete choice study in 1989, and has completed hundreds of such studies since, many using software he himself custom-developed. He has worked with end-clients in a wide variety of industries, particularly pharmaceuticals, but also including telecommunications, packaged goods, small appliances, financial services, information services and others; in areas including new product design and assessment, market sizing, pricing and market segmentation. Earlier experience with financial modeling and capital markets, together with three years in line management of a DP department of 35 employees, contributes to his understanding of clients’ broader concerns. Dave wrote the chapter on Pricing Research in Marketing Research: State of the Art Perspectives, and the prize-winning article “The Price Is Right (Or Is It?)” in the Winter 2002 issue of Marketing Research magazine. He has taught over 100 tutorials on pricing research and many on other topics, at a variety of conferences including the Advanced Research Techniques (ART) Forum. He chaired the 2002 AMA Marketing Research Conference and has served on the conference committees for the 2012 through 2021 Sawtooth Software Conferences, the 2023 and 2024 Analytics & Insights Summits, and the 2006 and 2011 ART Forums. His 2016 paper on Naïve Bayes Classifiers won the best paper award at the Sawtooth Software Conference. He is an honors graduate of Princeton University, where he majored in Statistics.
