I am a Postdoctoral Researcher in the Scalable Computing Systems (SaCS) lab at EPFL, Switzerland, led by Prof. Anne-Marie Kermarrec. I completed my PhD in Computer Science at INRIA and École Polytechnique in France, under the supervision of Prof. Catuscia Palamidessi. During my PhD, I have been a Visiting Scholar at the School of Computing at Macquarie University in Sydney, Australia (hosted by Prof. Annabelle McIver and Dr. Natasha Fernandes) and at WMG at The University of Warwick in Coventry, England (hosted by Prof. Carsten Maple and Prof. Graham Cormode).
My research primarily centres on designing distributed trustworthy systems for analysing data and training models in decentralised frameworks. Occasionally, I get fascinated by, and end up working on, some of the challenges of location privacy, aiming to build privacy-preserving and secure location-based systems. I focus on exploring and optimising the trade-off between privacy and utility from a foundational perspective. My current research revolves around decentralised learning, federated learning, and fair and trustworthy decentralized systems, with a particular emphasis on privacy and personalisation.
I study, talk, and do mathematics most of the time; when not, I am typically immersed in techno music, chess, cricket, philosophy, puzzles, or stand-up comedy. Lately, I’ve rekindled my love for (non-academic) reading and have become a collector of seemingly useless facts from all corners of life — because who doesn’t need to know how often penguins defecate? I am also trying to learn French with limited success so far. The list of some of my current favourite results and theorems in mathematics (a list that, obviously, everyone should maintain) includes:
