I am a postdoc researcher at EPFL (Switzerland) with an EcoCloud grant, collaborating with Carmela Troncoso at the SPRING lab and Martin Jaggi at the MLO lab. I achieved a PhD in Machine Learning and Information Security from Royal Holloway University of London with the Centre of Doctoral Training (CDT), where I was supervised by Alex Gammerman and advised by Kenny Paterson. I received an MSc in Machine Learning from Royal Holloway University of London in 2014, and a BSc in Mechatronics and Computer Engineering from University of Pavia in 2013.
My current research aims at measuring systems’ leakage by using methods from the Machine Learning theory; I applied this to side channel attacks (e.g., traffic analysis). I also worked on extending methods for confident prediction (e.g., Conformal Predictors), particularly in the context of clustering, anomaly detection, and classifiers ensembling.
