In a separate announcement, Ensemble Discovery said it has hired former 454 president and CEO Richard Begley as its new president and CEO.
New Haven, Conn.-based CuraGen said it has begun to look for a new CEO, and that Rothberg will remain in his position until a replacement is appointed. Rothberg has been the chairman and CEO of the pharmaceutical company since it was founded seven years ago.
According to CuraGen, Patrick Zenner, a member of the board of directors, has been asked to chair the search committee for the new CEO, and Rothberg said in a statement that he would assist in the search.
