Pierre Ganty

from 2019

I am an associate Research Professor at the IMDEA Software Institute doing research in the fields of verification, language theory and automata theory. You can find more about my research output on DBLP, Google Scholar, ORCID, and GitHub.

News

The language inclusion algorithm for Büchi automata introduced in our CAV’22 paper is part of Spot since version 2.12. Relevant details here.

Short Bio

Pierre joined the IMDEA Software Institute in September 2009 after completing a nearly two years postdoc at the UCLA. He holds a joint PhD degree in Computer Science from the Université Libre de Bruxelles and from the Università Degli Studi di Genova, Italy that he obtained late 2007.

Further details in my CV.
