Dr. Jürgen Deller’s research has created novel scholarship on later life work, the so-called “silver work,” showing the productive contributions of aging and near-retirement and postretirement workers to the economy. He has produced deep knowledge on expatriation and repatriation, examining adjustment and performance criteria, their determinants, and processes. His research, published in more than 50 refereed journal articles, more than 80 book chapters, and seven books, has had global readership and influence. Through his knowledge sharing, he has affected organizational practices in some of Europe’s largest multinational companies around expatriation, repatriation, older workers, refugees, and recent immigrants. His work has also influenced public policy discussions on silver workers throughout Europe, the Americas, and Asia.
