WASHINGTON — In the halls of US universities and research labs, one question has become increasingly common as President Donald Trump tightens his grip on science and education: whether to move abroad.

"Everybody is talking about it," JP Flores, a doctoral student in genetics at the University of North Carolina, told Agence France-Presse.

The discussion was thrust into the spotlight after Yale philosophy professor Jason Stanley, a specialist in fascism, announced he was taking a post in Canada due to the Trump administration's "authoritarian" bent.

"I made the decision when Columbia folded," he told CBS News. "I made it in a split second."

Columbia University, which the Trump administration has threatened with major funding cuts, said it agreed to take steps to rein in pro-Palestinian protests, among other actions.

"It is not the time to cower and fear," said Stanley.

With similar threats lodged against other universities, many researchers are worried about the future of academic freedom in the United States.

Coupled with the administration's broad cuts to federal funding, some fear the country's research field, once viewed as the envy of the world, maybe losing its luster.

More than 75 percent of scientists are now considering departing the country over Trump's policies, according to a survey of over 1,600 people published in late March by the journal Nature.

"The trend was particularly pronounced among early-career researchers," the journal said.

"People are just so scared," Daniella Fodera, a Columbia PhD student whose research grant was canceled, told AFP.

Amid the uncertainty, several academic institutions in recent weeks have announced a hiring freeze and a reduction in the number of graduate student positions.

"That's definitely messing up the academic pipeline," said Fodera, a biomechanics student.

Karen Sfanos, head of a research lab at Johns Hopkins University, said, "It's kind of a surreal time for scientists because we just don't know what's going to happen with funding."

Fodera, who studies uterine fibroids — benign tumors affecting many women — said she has begun to "actively look at positions in Europe and abroad for continuing my postdoctoral training".

With mounting concerns among US researchers, several European and Canadian universities have launched initiatives to attract some of the talent, though they may not need to try too hard.

"I know researchers already that have dual citizenship, or who have family in Canada, in France, in Germany, are saying, 'I think I'm going to go live in Germany for the next, you know, five years and do research there,'" said Gwen Nichols.

The physician, a senior leader at a blood cancer research group, warned the possible exodus could make the United States "lose our dominance as the biopharmaceutical innovation leader of the world".
