Theo Melas-Kyriazi, Director

Theo Melas-Kyriazi joined Flagship Pioneering as an Executive Partner in April 2019. Prior to joining the firm, Theo served as chief financial officer of Levitronix Technologies, a worldwide leader in magnetically levitated bearingless motor technology. Before Levitronix, Theo held a nearly two-decade career at Thermo Fisher Scientific, where he served in a variety of roles including Treasurer, CFO, and CEO of a publicly-traded Thermo subsidiary. As Treasurer and then CFO, Theo was instrumental in raising $2B in equity and convertible debt; executing 5 IPOs of Thermo subsidiary companies; and executing a broad restructuring that transformed TMO from a diversified holding company into a company focused on serving life science customers.

Over the last 20 years, Theo has served on the boards of multiple public and private healthcare and life science companies, including Moderna, Valeant Pharmaceuticals, Thoratec Corporation, Helicos Biosciences, and Evelo Biosciences. He also served as an operating partner of a middle-market private equity firm from 2007 to 2012.

Theo holds a bachelor’s degree in economics and an MBA from Harvard University.
