Flying insects provide an existence proof of low size, weight, and power (SWaP) goal-oriented autonomous agents that exhibit many of the same behaviors we desire in engineered systems. Our goal is to discover and understand the principles underlying the incredible performance of flying insects and apply those principles to the design of future Air Force systems. Biological sensing is multi-modal, robust, and efficient, employing distributed arrays of mechanical sensors, exquisite chemical detection, wide field-of-view multi-aperture optical systems, and inertial sensors. The neural processing of sensor information is fast, parallel, and efficient.
There are engineered mechanical sensors that can sense the same types of information as that being sensed by the biological sensors such as accelerometers, force and torque sensors, bending and shear sensors, pressure and flow sensors. In addition, there are cameras that are based on the principles of compound eyes that have been developed in recent years. But we are still a long way from being able to match the robust efficiency of the biological systems with engineered systems. One important aspect is the information processing or “algorithms” that the biological systems are using, and this is not very well understood yet. A deeper understanding of the underlying principles involved in the sensing and processing that enables the exceptional performance we observe in biological systems is needed in order to translate those design principles to engineered systems.
We are soliciting candidates with a passion to conduct research in any or all of the following areas:
1) the use of structure and information processing in natural systems, such as matched filters, to achieve efficient processing with high quality output, including anatomical mapping of sensory and processing circuitry in biological systems
2) concepts for information encoding and processing that are descriptive of biological sensory and neural processing systems, including the use of sparse and compressive sensing in biological systems;
3) measurements of the natural world stimulation available to biological systems (e. g. dynamic UV and broadband polarization wing signatures) and implementation of stimulation in biological experiments that closely match the natural world;
4) measurements of characteristics of invertebrate optical systems that uncover the underlying design principles (e.g. acuity maps);
