The university has many multi-disciplinary institutes devoted to research in varying fields, including the Medieval Institute, the Kellogg Institute for International Studies, the Kroc Institute for International Peace studies, and the Center for Social Concerns. Recent research includes work on family conflict and child development, genome mapping, the increasing trade deficit of the United States with China, studies in fluid mechanics, computational science and engineering, and marketing trends on the Internet. As of 2013, the university is home to the Notre Dame Global Adaptation Index which ranks countries annually based on how vulnerable they are to climate change and how prepared they are to adapt.
