Sensory science involves using senses such as smell, taste, touch, sight, and hearing to systematically gather information about the world. It may also include learning how these senses work and what applications exist for the discipline.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
