The Nobel Assembly at the Karolinska Institute is a body at the Karolinska Institute which awards the Nobel Prize in Physiology or Medicine. The Nobel Assembly consists of fifty professors in medical subjects at the Karolinska Institute, appointed by the faculty of the Institute, and is a private organisation which is formally not part of the Karolinska Institute. The main work involved in collecting nominations and screening nominees is performed by the Nobel Committee at the Karolinska Institute, which has five members. The Nobel Committee, which is appointed by the Nobel Assembly, is only empowered to recommend laureates, while the final decision rests with the Nobel Assembly.
