I am an applied scientist at Amazon Web Services working on issues around Responsible AI. In July 2022 I completed a PhD in Statistics at Carnegie Mellon University under the supervision of Alexandra Chouldechova and Zachary Lipton.

During the PhD, I interned at Microsoft Research working with Besmira Nushi, Kori Inkpen, and Eric Horvitz, and I spent seven months working as a research fellow at the Partnership on AI with Alice Xiang. Before joining CMU for my graduate studies, I was a student at the Collegio Carlo Alberto and at the University of Torino, where I was advised by Matteo Ruggiero. I received my ungraduate degree from the University of Padova, with an Erasmus exchange at the École Normale Supérieure de Cachan.

I am broadly interested in the application of statistical machine learning methods to the social sciences. My current research is driven by the following two questions:
• How does sampling bias affect the data on which risk assessment instruments are trained and and what are its consequences?
• How do experts integrate the recommendations made by risk assessment instruments into their decision-making processes?

When I'm not injured, I run and log some miles (kms) on Strava.
