Duan grew up in the Ramat Amidar neighbourhood of Ramat Gan and studied for a master's degree in social work and community administration at Bar Ilan University. He worked as a social worker at American Jewish Joint Distribution Committee and ran centres for occupational development for Ethiopian immigrants in Ashdod and Rehovot.
In 2008 he headed Shaul Mofaz's campaign for the Kadima leadership election. He was placed 33rd on the Kadima list for the 2009 Knesset elections. After failing to enter the Knesset as the party won 28 seats, he worked as a political advisor to Yulia Shamalov-Berkovich. On 25 January 2012 he entered the Knesset as a replacement for Eli Aflalo, who resigned after becoming co-chairman of the Jewish National Fund. Duan also acted as Mofaz's campaign manager for the 2012 Kadima leadership election.
He lost his seat in the 2013 elections.
