Sensing and decision-making

Organisms make decisions in the face of uncertainty, implying that decision-making in nature requires statistical inference. How do organisms parse noisy data streams? How do they use these data to decide what to do? We model organismal decision-making using statistical inferential frameworks combined with tools from neuroscience and ethology. Our goal is to understand why natural selection has led to the decision-making strategies we see in nature and how such rules operate in natural environments.
