Timothy Kuklo, a researcher and professor at the Washington University School of Medicine, has voluntarily resigned after allegedly falsifying a study, a medical school spokesman confirmed Wednesday evening.

Kuklo, associate professor of orthopedic surgery, submitted a letter of resignation on July 30, effective Sept. 30, according a statement issued by the University.

“Dr. Kuklo has agreed to voluntarily resign from the University, effective September 30, 2009,” the statement said. “Dr. Kuklo will have no clinical, research, or educational duties for the University between now and that date.”

Kuklo has been the subject of several federal inquiries over a study he allegedly falsified while he worked at Walter Reed Army Medical Center. He performed the study, which was about the benefits of a bone growth drug, before coming to the University.

Medical school spokesman Don Clayton declined to comment further because school officials are conducting an investigation.
