The Jews of Khazaria is an accessible introduction to Khazaria--a kingdom in the early Middle Ages noted for its adoption of the Jewish religion. The third edition of this modern classic features new and updated material throughout, including archaeological findings, genetic (DNA) evidence, and information about the migration of the Khazars.

He contributed an article about the Khazars to The Encyclopaedia of Judaism, second edition, and wrote an introduction for Rabbi Daniel Korobkin's translation of The Kuzari. He also researches Sephardic Jewish migrations throughout the world and the presence of Jewish ancestry among Latin Americans, Sicilians, and Slavs. His website is Khazaria.com.
