New England Biolabs chief scientific officer Richard Roberts has joined the faculty of Northeastern University as a professor based at the Marine Science Center in Nahant. Roberts is a biochemist and molecular biologist credited with the codiscovery of split genes — research that advanced the knowledge of DNA and for which he received a Nobel Prize in Physiology or Medicine in 1993. According to a press release, the appointment coincides with relocation of the marine DNA repository called Ocean Genome Legacy to the Nahant facility. Director Dan Distel said the legacy project is like a DNA library that catalogues samples of organisms from all over the world, to be made available to scientists for research. It was founded in 2003 as a nonprofit organization based at Ipswich-based New England Biolabs, which remains a major sponsor.
