My CV.
Email: sophia.knight at gmail.com
I am a postdoctoral researcher at Uppsala University in the Theory for Concurrent Systems group. My research focuses on analysing the flow of information between interacting agents, particularly in security applications such as anonymity protocols. I have studied this problem from various perspectives: various modal logics with an epistemic focus, process algebra, games, and topological models. I am currently working on a logic for analyzing the effects of asynchronous communication on knowledge as well as an ATLstyle 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 have worked on topological semantics for dynamic epistemic logics.
From 2013 to 2016, I was a postdoctoral researcher at LORIA at Université de Lorraine, in Hans van Ditmarsch's CELLO team.
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, using game semantics, modal logic, and process calculus.
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.
