Animal decision-making & bayesian learning

Organisms make decisions in the face of uncertainty, implying that all decision-making mechanisms that involve sensory data require statistical inference. How do organisms parse noisy data streams? How do they use these data to decide what to do? I model organismal decision-making using statistical inferential frameworks to understand why natural selection has led to the decision-making rules we see in nature.
