Pierre-Louis Roman

Hi, I am a postdoc in the Distributed Computing Lab lead by Rachid Guerraoui at EPFL. I try to improve the security and efficiency of large-scale distributed systems such as distributed ledgers and cryptocurrencies.

I was previously a postdoc working on the security and efficiency of datacenter systems in the SWYSTEMS group lead by Patrick Eugster at USI Lugano. I completed my PhD on large-scale decentralized systems in 2018 supervised by François Taïani and Davide Frey at the WIDE group of Université de Rennes - Inria - IRISA and partly by Spyros Voulgaris during my summer at VU Amsterdam. Earlier, I received a BSc in 2011 and an MSc in 2013 both in computer science from Sorbonne Université.

Interests: Distributed systems, System security, Distributed ledgers and blockchains, Operating systems.
