New England Biolabs Leadership


Dr. Don Comb

Donald Comb

Founder & Chairman of the Board
Ph.D., University of Michigan

Prior to taking a position at Harvard Medical School, Don attended the University of Michigan where he earned a Ph.D. in epidemiology. Don’s commitment to science led to the inception of New England Biolabs in 1974. His scientific vision shaped NEB as the leader in the discovery and production of recombinant enzymes for molecular biology applications.

Don’s passion for science, art and the environment has also led to the creation of the New England Biolabs Foundation, a program that promotes environmental awareness and social change; and the Ocean Genome Legacy Program, which he believes will help to prevent the extinction of endangered sea life. His commitment to the environment is evident on the NEB campus; from the LEED certified laboratory that was designed to minimize its impact on the surrounding landscape, to the Solar Aquatics System®, designed to treat the campus’ wastewater. Don’s beliefs are deeply woven into the corporate philosophy; as a result, New England Biolabs has had the honor of being lauded with the “2009 Recycling Business Award” and the “2010 Best Places to Work” award by "The Scientist" magazine.

Although Don has stepped down from his position as CEO, he continues to serve on the Board of Directors. Don also maintains an active research laboratory at NEB. His interests include parasitology, epigenetics and the development of biofuels. Don’s current research focus involves the isolation and biochemical characterization of novel cellulases.
