Some of the grants paid for military-specific medical research, studies on countering weapons of mass destruction and research on lasers, among numerous other topics, Reuters found.
The abrupt halt stopped years-long projects and upended programs spread across several universities, not just Harvard. In 2025 alone, an estimated 103 grants totaling about $14 million will grind to a halt, according to an analysis by Govini, a defense software company.For example, US officials ended Harvard School of Engineering and Applied Sciences Professor Katia Bertoldi’s $6 million Pentagon-funded project developing shape-changing structures with military applications two weeks ago, despite being at a critical juncture in its research cycle.
“We’ve been in year three, so we set up all the tools, and now we’re really gaining momentum, and now it stops,” Bertoldi said.
Funded through the Department of Defense’s Multidisciplinary University Research Initiative, she was developing technology based on origami that would lead to reconfigurable antennas, and deployable shelters like field hospitals.
Since 2020 the Pentagon, Defense Advanced Research Projects Agency and every branch of the US military have given Harvard 418 grants valued at $180 million, according to the analysis by Govini.
Secretary of Defense Pete Hegseth “directed the termination of several programs, contracts and grants that were not aligned with the Department’s priorities to cut wasteful spending, implement the President’s orders, and reallocate savings to mission-critical priorities,” a Pentagon spokesperson told Reuters.
The bulk of those grants went to military medical research, basic scientific research and applied scientific research, Govini found, with the Army providing the most funding.
The administration has frozen approximately $3 billion in federal grants to Harvard, with Trump complaining on Truth Social that Harvard has hired “Democrats, Radical Left idiots and ‘bird brains’” as professors. On Monday, Trump said he is considering redirecting billions of dollars of previously awarded scientific and engineering research grants from Harvard to trade schools.
Harvard has sued to restore the funding, calling the cuts an unconstitutional attack on its free-speech rights.
The research cancellations affect extensive collaborative networks. Bertoldi’s project included researchers from the University of Pennsylvania and Georgia Tech.
Scientists warn these cuts may have strategic implications as China has heavily invested in research.
Bertoldi said, “In China, as far as I know, colleagues that moved back to China, there’s a lot of support for this type of research.”
