Professor Liu’s research focuses on consumer behavior, particularly as it relates to consumer welfare and well-being. She primarily conducts research in three substantive areas, with a common theoretical focus on quality versus quantity aspects of consumption (e.g., "what" vs. "how much" to consume).
- Health: Factors that shape the healthiness of consumers' choices and consumption, especially in the food domain. Dr. Liu's focus is on how food type versus food quantity changes are differentially perceived and preferred, and the impact of jointly varying both food type and food quantity.
- Social: Factors that shape consumers' social connections. Dr. Liu's focus is on (i) how consumers make choices for each other and the impact of these choices and (ii) when and why consumption acts are a source of offense to other consumers. For instance, when and why do consumers favor product quality versus quantity when choosing for others?
- Health & Social: How consumers jointly manage their personal and interpersonal goals.

She has also co-authored op-eds in The Washington Post’s Monkey Cage blog about her research on public policy issues.
