Symbolic dynamics; Cellular automata
I am a university lecturer at the Department of Mathematics and Statistics. I obtained my PhD from the University of Turku in 2015. Since then I have worked as a researcher at Boston University (USA), University of Montpellier (France), and now at the University of Turku.
I study cellular automata and multidimensional symbolic dynamics, from both dynamical and computational perspectives. In particular, I am interested in the properties of multidimensional SFTs and sofic shifts, and the relations between their different subclasses.
I regularly teach courses on Euclidean geometry, linear algebra and the Finnish high school mathematics curriculum for teachers.
