Research interests

I use neuroimaging, computational modeling, and brain-machine interfaces in order to study temporal uncertainty and causal inference in perception and action. In particular I am interested in the unconstrained detection of and reaction to uncertain events in continuous time. In the limit, where sensory evidence is nil, this leads to the mystery of spontaneous self initiated movement: when do I make my next movement and how does this decision emerge in the brain in the absence of an external imperative? My research to date has focused on identifying specific correlates of near-threshold sensory perception, and on the neural antecedents of self-initiated movement. A further goal is to integrate these two areas of research in the study of foraging behaviors in humans and other animals. I am very keen on machine learning and signal processing techniques for data analysis, as well as diffusion and recurrent neuronal network models.
