Ed Husain, the Muslim co-founder of a British counter-extremism organisation, is to take the "battle of ideas" to America.
Mr Husain, 34, who set up the Quilliam think tank in 2007, will leave the organisation this November to become a senior fellow at the US Council for Foreign Relations (CFR).
He is also planning to take on an academic role at an American university and work on a follow-up book to The Islamist.
In his first book, the London-born writer described his five-year involvement with the Islamic fundamentalist group Hizb ut-Tahrir, an experience which led to the formation of Quilliam.
Quilliam will now be led by Maajid Nawaz, another former member of Hizb ut-Tahrir.
Praising the work of his colleague, Mr Nawaz said: "Quilliam's vast output has contributed to improving civil society debates around terrorism.
"Islamists in Britain are today discredited and unable to muster a coherent argument in defence of their confrontational causes, while the majority of normal Muslims are quietly finding ways to respond to the challenges of life in a secular, liberal society.
"Much of this was made possible by Ed Husain."
