US president-elect Joe Biden has chosen decorated geneticist Eric Lander as presidential science adviser and director of the Office of Science and Technology Policy (OSTP). Many scientists have long called for the OSTP director to be raised to a cabinet-level position. When Biden named Lander to his team on 15 January, he also announced a number of other respected scientists to key positions in his administration. One major question is what parts of science policy Lander and his office will be responsible for. The outgoing OSTP director, meteorologist Kelvin Droegemeier, wasn’t appointed by President Donald Trump until more than a year and a half into his administration.
