Dr. Tristram Wyatt is a senior researcher at the Department of Zoology, University of Oxford and an emeritus fellow of Kellogg College, Oxford.

He is interested in how pheromones evolve throughout the animal kingdom, at both molecular and behavioral levels.

The second edition of his book Pheromones and Animal Behavior will be published by Cambridge University Press in late 2013.

In his TED talk "Success of the smelliest?

Do humans have pheromones?," Dr. Wyatt touches upon the sense of smell.

Moths, goldfish, snakes and fruit flies all react to pheromones (chemicals for communication).
