Understanding markets in the age of AI.

I study how artificial intelligence, recommender systems, data-driven algorithms, and algorithmic pricing reshape decisions by firms and consumers. My work combines economics and machine learning to understand the opportunities and risks created by digital technologies.

A parallel stream of my research examines consumer protection, data governance, and responsible market design in the digital age.

Algorithmic Markets

How algorithms change competition, pricing, disclosure, and the strategic choices of firms.

02

AI & Consumer Decisions

How intelligent systems, recommendations, and automated agents influence consumer behavior.
