Dr Alex Stewart
Dr Alex Stewart has retired from his Consultant post in Health Protection in the Cheshire and Merseyside Public Health England Centre. Previously, he worked for many years in the Northern Areas of Pakistan, where his interest in iodine deficiency developed. He is particularly interested in the links between the environmental distribution of iodine and the deficiency disorders.
