Riccardo Tommasini
A passionately rational man.
I am a Maître de Conférences (Associate Professor) at the Institute National des Sciences Appliquées (INSA) one of France’s leading engineering schools situated in Lyon
In particular, I am member of the DB Team at LIRIS, lead by Prof. Angela Bonifati.
I have a Ph.D. in Computer Science, obtained from the Department of Electronics and Information of the Politecnico di Milano, under the supervision of Prof. Emanuele Della Valle. My Ph.D. dissertation, titled “Velocity on the Web”, investigated the velocity aspects that concern the Web environment. Together with Prof. Della Valle and Prof. Pieter Bonte, it converged in a book in 2021.
My research is centered around Stream Processing, with connections to Distributed Systems, Event Processing, Formal Founations, as well as Graph Databases and Knolwedge Graphs. For further insight into my research philosophy, please refer to this statement outlining my work and objectives.. Altenavtively, you can check the list of publications

Prior to joining INSA I was an Assistant Professor at the University of Tartu, Estonia. I was member of Data System Group, founded by Prof. Sheri Sakr (R.I.P.). From April 2020 until February 2021, I was the group ad-interim head given his premature demise.
During my career I also developed several industrial collaborations both for research and consulting with with Neo4j, InfluxData, and Confluent Inc, Bloomberg.
I negotiated and managed two research projects with the Nordic Institute for Interoperability of Software (NIIS). The projects (one of which is still ongoing) focuses on X-ROAD, the backbone of Estonia and Finland’s e-government infrastructure.
