Andreas Keller is a New York-based academic with PhDs in neuroscience and philosophy who is interested in olfactory perception. He has over a decade of experience in olfactory psychophysics and the clinical aspects of olfaction. The results of his experiments have shed light on human olfactory capacities, on the relation between the structure and smell of odor molecules, and on the perceptual consequences of variability in odorant receptor genes. He is the author of The Philosophy of Olfactory Perception, in which he explores the philosophically interesting differences between seeing and smelling, and the owner of Olfactory Art Keller, an art gallery in New York’s Chinatown that is dedicated to the exploration of scent as a creative medium.
