Collins, who was appointed by President Obama in 2009, has said he would like to keep the job. He met with Trump last week in New York. Among the others said to be in the running to head the huge biomedical research agency are Rep. Andy Harris (R-Md.) and biotech entrepreneur Patrick Soon-Shiong.
The Trump transition team has asked some 50 senior Obama administration officials to stay at least temporarily to ensure continuity in government.
If he is not asked to stay permanently as director, Collins, a geneticist, is planning to return to his NIH lab.
