Then, could you tell me which one is preferred between "She [ had researched / had been researching ] the human genome for ten years when she became the laboratory chief"?

Both versions are grammatically correct, but it isn’t clear what you want the sentence to say: Did she quit researching when she became chief? If so, use “She had researched…’ and if instead she continued to research after becoming chief, use ‘She had been researching…’
