Decision, Risk and Operations
Yuri Fonseca
I am a PhD candidate in Decision, Risk, and Operations at Columbia University. I am privileged to be advised by Professor Omar Besbes and Professor Ilan Lobel from NYU-Stern. My research interests include online optimization, decision-making, and learning in complex environments like online platforms and marketplaces. I am passionate about innovation, entrepreneurship, and how machine-learning methods can be employed to address decision-making problems.

Sonia Seung-Eun Kim
I am a consumer behavior researcher interested in finding ways in which marketers can contribute to bridging people together. Specifically, my research focuses mainly on understanding the psychology behind (1) the social dynamics of consumers and (2) the way consumers exert or avoid autonomy in the marketplace, with the goal of providing novel insights and interventions for firms to maximize consumer welfare.
Shin Oblander
I am an empirical methodologist focusing on statistical and econometric methods. In my prior work, I develop methods for selection correction and causal inference with customer base panel data. Currently, I am working on projects based around representation learning methods for unstructured data and empirical modeling of boundedly rational behavior.
Alisa Yinghao Wu
My research interest primarily lies in obtaining information from textual data about consumer behavior and psychology, with a focus on the interplay between emotions and cognitive processes. I work with user-generated content (e.g., online reviews, conversations, thought-listings) to understand how the properties of language can predict consumers’ post-sharing feelings and revisit intentions, cognitive performance (e.g., creativity), and decisions (e.g., when to claim their social security benefit).
