Vitor Hadad
Applied Scientist (L5)
Amazon Lab126


I'm an applied scientist at Amazon Lab126, where I use machine learning-based causal inference and prediction methods to solve problems related to Amazon devices. Recently I've worked on sleep-related devices such as the Amazon Halo Rise.

Prior to this position, I was a postdoc at the Golub Capital Social Impact Lab, led by Susan Athey at Stanford GSB. My research focused on the design and analysis of adaptive experiments such as multi-armed bandits and contextual bandits. I was a developer on the R package grf for nonparametric causal inference based on random forests.

I hold a PhD in Economics from Boston College. My advisors were Stefan Hoderlein, Arthur Lewbel and Utku Ünver.
