Nail Hassairi

I am a quantitative researcher with a decade of experience at the intersection of economics, data science, and early childhood education policy.

My work spans causal inference, program evaluation, large-scale survey design, and machine learning—applied to questions that matter: How do we measure the quality of care young children receive? What drives disparities in access and outcomes? How can data move policy?

I hold a PhD in Economics from the University of Washington and have worked as a data scientist at Amazon, where I built analytics infrastructure for experimentation at scale. My research has been published in journals including Education Finance and Policy, PLOS ONE, Early Education and Development, and the Journal of Applied Developmental Psychology.

Before all of this, I was born in Zaghouan, Tunisia. I grew up in Prague, studied economics at Charles University, and crossed the Atlantic on an exchange program that became a fifteen-year chapter in Seattle. I now live in Prague again—Holešovice—where the work continues.
