Washington University in St. Louis has told a Senate committee that Timothy K. Kuklo, a physician who is on leave from the university, failed to report for a year his ties to Medtronic even as he was conducting company-sponsored research, The New York Times [1] reported. Kuklo is at the center of a controversy over research that has since been discredited amid allegations he falsified parts of a study. Kuklo has declined to comment on the situation, or the Washington University finding.
