How does an immigrant become an American? How does anyone join any group? SAPIENS host Esteban Gomez shares the story of Dr. Morwari Zafar, a researcher who has studied the changes in her own community of Afghan-Americans in Fremont, California, in the wake of 9-11. From the first major wave of immigration in the late 1980s and early 1990s, to 9-11 and the U.S. invasion of Afghanistan, the Afghan-American community has been in flux, exemplifying the mysteries of group identity, dynamics, and nationhood.    Morwari recently completed a PhD in anthropology at Oxford University. Her PhD dissertation is available online: COIN-operated anthropology: Cultural knowledge, American counterinsurgency and the rise of the Afghan diaspora. Zafar is now managing partner at Sentient Group, a consulting company focused on the national security, international development, and private sectors.
