Hi! Thank you for visiting my website.

I am a causal ML economist at Amazon. I build experimental and observational frameworks to provide data-driven recommendations to advertisers on Amazon. 

Prior to Amazon I did research at the World Bank, where I published a paper on the relationship between self-employment and migration in developing countries (with David McKenzie), and at the Rhode Island Innovative Policy Lab (RIIPL).

In 2021, I graduated with a Ph.D in Economics from Brown University. In my dissertation (published in the JDE), I applied tools from the industrial organization and development economics literature to study the role played by political connections in the allocation and execution of procurement contracts in Ecuador.
