Ms. Wahdan focuses on Muslim Sunni, Salafist and Shia’ radical groups and terrorist organizations. She is an American-Arab born and raised in Kuwait for fourteen years. She gained a tremendous understanding to the radicalization process and the ideology that exists in the Middle East while being exposed to religious, cultural and governmental differences in the region.
