Holliston-based biotechnology firm Harvard Bioscience has elected a new member to its board following the departure of director Thomas Loewald.

Loewald stepped down from his directorial role on Friday after serving as a board member since October 2017, according to a Monday press release and filing with the U.S. Securities and Exchange Commission. 

“On behalf of the entire board, I thank Tom for his service. It has been a privilege to have worked alongside Tom over the last seven and a half years, and I wish him all the best,” said Katherine Eade, Harvard Bioscience’s new lead independent director of the board, in the press release. 

Loewald’s departure comes after the CFO of the company resigned in May, after it reported a net loss of $12.4 million from fiscal 2024. In April 2024, the company implemented $4 million in layoffs. 

John Duke was appointed as Loewald’s successor, effective Monday, and will serve on the company’s audit, and nominating and governance committees. 

In addition to his board role, Duke is CEO of Plastic Molding Technology, a Texas-based plastics manufacturer. 

“The combination of John’s operating experience along with his strong technical and business background make John an excellent addition to our board,” Jim Green, Harvard Bioscience’s president and CEO, said in the release.

Duke has spent the past 30 years in leading manufacturing roles, including serving as executive vice president and chief business officer at Lyten, a California-based advanced materials manufacturer, and a number of positions throughout his two decades with Corning, a New York-based glass, ceramics and concrete manufacturer.

Duke graduated with his bachelor’s degree in materials science and engineering from the University of Utah and his MBA from Harvard University in Cambridge.

“I am honored to join Harvard Bioscience’s board at this important time. I look forward to working with the company’s leadership team and my fellow directors to overcome current challenges and deliver growth,” Duke said in the release.
