About Me
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. Prior to that, I studied mathematics at the University of Bath in the UK, where I obtained my M.Math with a First-Class Honours. 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 secure and trustworthy distributed systems for analysing data and training ML models in decentralized frameworks. My current research interests revolve around decentralized learning, federated learning, and trustworthy distributed systems, with a particular emphasis on aspects of privacy, fairness, and personalization.
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:
