Our focus is on understanding the foundations and techniques for information processing in networked sensory systems. Such systems perform tasks that involve reliable communication and distributed computation in the presence of constraints such as severely limited energy, channel noise, interference, and malicious jamming. For applications as diverse as wireless sensor networks and cognitive functions in organisms, we are investigating the fundamental bottlenecks that determine the maximum amount of insight that can be provided by a sensing modality.
