My name is Sílvia Casacuberta Puig and I am a student from Barcelona pursuing a joint AB degree in Mathematics and Computer Science with a concurrent masters (SM) in Computer Science at Harvard University (Massachusetts, USA).
I am broadly interested in theoretical computer science, including matrix and graph algorithms, cryptography, data privacy, and algorithmic fairness.
