Instances of Scientific Misconduct

Jun Iwamoto

Jun Iwamoto is infamous for having around 74 retractions of studies/publications. Iwamoto worked alongside Yoshihiro Sato (also featured on this site), another bone-health specialist. Jun Iwamoto, originally a board member of the Osteoporosis Society of Japan, is known for having retractions due to duplications of data and articles, errors in text, general misconduct, false/forged authorship, and concerns about results and data. Much of his work was in orthopedics, cellular biology, toxicology, endocrinology, etc. Many of his retracted or rejected papers were in JAMA Internal Medicine, Journal of Bone and Mineral Research, Neurology, and Trials
