About

I'm a Senior Research Scientist at Nokia Bell Labs in Cambridge, where I invent and build efficient solutions for machine learning. My area of expertise? It's all about federated learning, making ML work harder with less, and tackling the tricky stuff like uncertainty estimation. Essentially, I'm working on the algorithms and systems that are going to make machine learning models faster, better, and more reliable for everyone.

I completed my Ph.D. in Computer Science at the University of Cambridge, under the supervision of Prof. Cecilia Mascolo. My research focused on developing techniques to provide efficient, accurate and uncertainty-aware mobile sensing and health applications. The goal was to enhance these applications with the robustness needed to withstand real-world challenges, such as distributional shifts and adversarial attacks.

Starting my journey at the University of Bologna, where I earned my BEng and MEng in Computer Engineering, I've since gathered diverse experience across the tech industry. My roles have ranged from research in ML-based user behavior analysis at T-Labs, efficient ML at Nokia Bell Labs, and adversarial mitigation at Arm, to software engineering in high-performance computing at Ellexus (now Altair), open-source data analytics at Connected Places Catapult, and spatial analytics at GeoSpock.
