Research interests

My current research focuses on questions concerning human spatial navigation behavior. My work is centered around the question: How do Humans get from point A to B?

More specifically, I’m interested in how humans represent their own belief about where they are in the world and how they use it to inform their navigational decisions. I combine work from navigation experiments in virtual environments with probabilistic computational models in order to understand complex navigation behavior, where information from multiple sources is integrated over time and space.
