Research Methodologies

I spend a lot of time thinking about how to improve experimental, survey and statistical methods to better understand how consumers will actually react to food policies and marketing. This research led to investigate some new consumer research methods such as experimental auctions, multiple price list, choice experiment, projective mapping, partial-least square regression, and conjoint analysis.
