I am an economist trained in empirical industrial organization. I study how data and AI technologies create and distribute economic value in imperfect markets.

I focus on applications in insurance and digital platforms, combining economic theory, causal inference, and modern computation methods to extract insights from large datasets.

My name is pronounced as "ee-joh jin."
