Dr. Peter John Hogarth is the senior lecturer in biology at University of York, in the United Kingdom. For years, Hogarth has been fascinated by the history of biology and what he calls the "un-natural history" of mythical creatures and belief in them. Hogarth's interest and in-depth study of dragons, in particular, has led him to write a number of books and articles covering the ecological aspects of dragons, the evolution of St. George as a dragon-slaying saint and dragon mythology in general. He has also given frequent talks and occasional broadcast interviews on the biology of dragons, giants and other mythical beasts.
When he is not pondering the mythical biology of dragons and other such creatures, Hogarth's main research interests are tropical marine biology, particularly the ecology and diversity of crustaceans, and the ecology of mangrove habitats. He has worked in Pakistan, China, Malaysia, the Maldives, Yemen, Egypt, Oman and the United Arab Emirates. He has also studied the effects of irrigation and related schemes on coastal ecosystems and fisheries in the Indus Delta (Pakistan), and of the impact of a major barrage on the lower Indus.
