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.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.
