Psychiatrist Ian Stevenson, from the University of Virginia, investigated many reports of young children who claimed to remember a past life. He conducted more than 2,500 case studies over a period of 40 years and published twelve books, including Twenty Cases Suggestive of Reincarnation and Where Reincarnation and Biology Intersect.
Stevenson methodically documented each child's statements and then identified the deceased person the child identified with, and verified the facts of the deceased person's life that matched the child's memory. He also matched birthmarks and birth defects to wounds and scars on the deceased, verified by medical records such as autopsy photographs, in Reincarnation and Biology .
Stevenson searched for disconfirming evidence and alternative explanations for the reports, and believed that his strict methods ruled out all possible "normal" explanations for the child’s memories.

However, a significant majority of Stevenson's reported cases of reincarnation originated in Eastern societies, where dominant religions often permit the concept of reincarnation. Following this type of criticism, Stevenson published a book on European Cases of the Reincarnation Type. Other people who have undertaken reincarnation research include:
