The long wait for a White House science adviser is over. President Donald Trump announced today that he intends to nominate meteorologist Kelvin Droegemeier, a university administrator and former vice-chair of the governing board of the U.S. National Science Foundation (NSF), to be director of the White House Office of Science and Technology Policy (OSTP). The OSTP director traditionally, but not always, also holds the title of the president’s science adviser.
