PhD student working on blockchains, epidemic protocols and eventual consistency.
I joined the ASAP research group in October 2014 under the supervision of François Taïani and Davide Frey.
I received a BSc in Computer Science in 2011 and an MSc in Distributed Systems in 2013, both from Université Pierre et Marie Curie (Paris, France).

Research interests

Decentralised systems and algorithms, blockchains, epidemic protocols, consistency models, social networks, banana-splits, privacy.


I spent three months, from June to August 2016, at the Vrije Universiteit Amsterdam (The Netherlands) working with Spyros Voulgaris on blockchain technologies.

Local activities

I am a member of the centre committee and of the training committee of IRISA/Inria Rennes.
