Ten Lost Tribes
Weil has published extensively on the Ten Lost Tribes historically and in contemporary times. In particular, she has written on the Beta Israel, the Bene Israel, and the Pashtuns, as well as on Judaising groups all over Africa, China and elsewhere. In 1991, she curated an exhibition at Beth Hatefutsoth: the Museum of the Jewish Diaspora on the Ten Lost Tribes entitled "Beyond the Sambatyon: the Myth of the Ten Lost Tribes". She is on the international board of ISSAJ [International Society for the Study of African Jewry], and presented a paper at their latest conference in Nairobi on the Jews of Africa.
