I am a postdoctoral researcher at LORIA at Université de Lorraine, in Hans van Ditmarsch's CELLO team. I am funded by CNRS. My research interests are modal logic, concurrency, games, topological reasoning, and security. I am currently working on a logic for analyzing the effects of asynchronous communication on knowledge as well as an ATL-style logic for modelling agents' abilities and knowledge under uncertainty. I am also developing a constraint programming language with modal information, in order to reason about knowledge and information flow among agents in a distributed system. Finally, with Aybüke Özgün I am working on topological semantics for dynamic epistemic logics.
I received my PhD in 2013 from LIX at Ecole Polytechnique.
My supervisors were Frank Valencia and Catuscia Palamidessi.
I was in the COMETE team. My dissertation analysed the flow of information between interacting agents,
particularly in security applications such as anonymity protocols. I
studied this problem from various perspectives: modal (epistemic) logic, process
algebra, and games.
I received my Master's degree from McGill University's School of Computer Science in 2009.
My supervisor was Prakash Panangaden.
I was in the Reasoning and Learning Laboratory.
My thesis was about a game semantics for a
process algebra modelling information flow between agents in anonymity
protocols. I also worked on developing an epistemic temporal logic.
