Today, Kelek is in demand as an expert on the subject of Islamic culture in the Western world. In her publication, "Die verlorenen Söhne" (The Lost Sons, 2006), her central theme is the influence of Islam on the small family. The book is based on Kelek's research project on the subject of "parallel society" at the "Evangelischen Fachhochschule für Sozialpädagogik" in Hamburg. Here also, Kelek merges autobiographical details, observations, conversations with Turkish retirees, and the results of interviews with Turkish prison convicts. She counsels the Hamburg justice authorities on questions about the treatment of Turkish Muslim prisoners. In preparation for the Deutscher Evangelischer Kirchentag 2005 in Hannover, she was invited to participate in the project group. In addition, she counseled the Baden-Württemberg state government regarding their legislative initiative to make forced marriage a punishable offense. She is a permanent member in the Islamic Conference appointed by the German federal government, and a free-lance author for the women's magazine, "Emma", and many daily newspapers, among others.
