Cristina Menghini

Ciao visitor, this is Cristina! ๐Ÿ‘‹

Iโ€™m a postdoc in the Computer Science department at Brown University ๐Ÿ‡บ๐Ÿ‡ธ, where I do fun research in the BATS lab led by Stephen Bach. As data is changing our notion of the world, I contribute to this change by either designing models to learn from a few labeled data, or understanding humans behaviours, with a computational approach.

I arrived at Brown as Visiting Ph.D. student and worked with Eli Upfal and Matteo Riondato. In July 2021, I defended my Ph.D. thesis in Computer Engineering from Sapienza University ๐Ÿ‡ฎ๐Ÿ‡น, advised by Aris Anagnostopoulos and Stefano Leonardi. I earned my masterโ€™s degree in Data Science at Sapienza University, after one-year exchange in the School of Computer and Communication Sciences at EPFL ๐Ÿ‡จ๐Ÿ‡ญ, where I joined Data Science Lab led by Robert West. Before that, I got a bachelor degree in Statistics, Economics and Finance at Sapienza University.
