I’m a Ph.D. candidate in Marketing at the Robert H. Smith School of Business, University of Maryland, where I am fortunate to be advised by Professor Jie Zhang. My research studies sustainable luxury retailing, with a methodological focus on causal inference and causal machine learning.

Before my Ph.D., I founded Zeta Technologies, a data science startup that built sales forecasting and customer lifetime value (CLV) models for jewelry and apparel retailers. That work keeps my research close to the questions luxury retailers actually face.
