Newsweek writes about Dr. Alex Rhys-Taylor, a London Ph.D. in sociology who explores food origins in his 2017 book,"**Food and Multiculture: A Sensory Ethnography of East London.*" 'He uses smell, taste, and other senses to explore how people of all ethnicities and classes intermingle in the city," according to Newsweek.
He has also written about jellied eels, haggis pakora and an olfactory history of London.
Linked below are the 5/6/17 Newsweek article, a six-minute youtube video, a book description and downloadable papers written by Rhys-Taylor.
