"As one of the world's leading physician-scientists and oncology executives, Dr. Gilliland's extraordinary knowledge of all aspects of oncology and gene therapy have been invaluable to Labcorp," said Adam Schechter, chairman and CEO. "We are grateful for his service of more than 10 years and unwavering commitment to advancing our mission to improve health and improve lives."

He also was a member of the faculty at Harvard Medical School for nearly 20 years.

"Dr. Gilliland's leadership, strategic insight and valuable perspective have been instrumental in strengthening Labcorp," said Dr. Garheng Kong, lead independent director and chair of the Nominating and Corporate Governance Committee.
