Pierre-Louis Roman

Postdoctoral researcher

Università della Svizzera italiana

I am a postdoctoral researcher in the Computer Systems Institute of USI Lugano, working with Patrick Eugster since 2019-08. I work on distributed systems with a focus on large-scale decentralized systems and distributed ledgers (e.g., blockchains).

I received a BSc in 2011 and an MSc in 2013 both from Sorbonne Université, and a PhD in 2018 for my work on decentralized systems performed under the supervision of François Taïani and Davide Frey in the WIDE group of Université de Rennes. I also spent the summer of 2016 at the Vrije Universiteit Amsterdam working with Spyros Voulgaris on Bitcoin.
