U.S. doctoral programs in electrical engineering form the foundation of technological advancement, training the brightest minds in the world to research, develop, and design next-generation electronics, software, electrical infrastructure, and other high-tech products and systems. Elite institutions have long served as launchpads for the engineers behind tomorrow’s technology.

Now that foundation is under strain.

With U.S. universities increasingly entangled in political battles under the second Trump administration, uncertainty is beginning to ripple through doctoral admissions for electrical engineering programs. While some departments are reducing the number of spots available in anticipation of potential federal funding cuts, others are seeing their applicant pools shrink, particularly among international students, who make up a significant portion of their programs.

In 2024 alone, U.S. universities awarded more than 2,000 doctorates in electrical and computer engineering, according to data from the National Center for Science and Engineering Statistics. The number of computing Ph.D.s grew significantly in the 2010s, according to data from the National Academies, but there is still high demand for those with advanced degrees across academia, government, and industry. Now, some universities point to warning signs of waning enrollment.

Though not all engineers have Ph.D.s, if enrollment continues to shrink, fewer doctoral students could mean fewer engineers developing cutting-edge technology and training the next generation, potentially exacerbating existing labor shortages as global competition for tech talent intensifies.

Federal funding cuts affect admissions

Public universities in particular are feeling the strain because they rely heavily on federal grants to support doctoral students.

The University of California, Los Angeles, for instance, must fund Ph.D. students for the duration of a degree—typically five years. In August 2025, the U.S. government pulled more than US $580 million in federal grants over allegations that the university failed to adequately address antisemitism on campus during student protests. A federal judge has since ordered the funding to be restored, but faculty began to worry that research support could be clawed back without notice, says Subramanian Iyer, distinguished professor at UC Los Angeles’s department of electrical and computer engineering.

According to Iyer, departments across UC Los Angeles, including engineering, plan to scale back Ph.D. admissions this year. “The fear is that at some point, all this government money will be taken away,” Iyer says. “Lowering the admissions rate is just a way to prepare for that reality.”

In response to a request for comment, a spokesperson for the U.S. National Science Foundation—a major source of federal research funding at UC Los Angeles and elsewhere—said, “NSF recognizes the essential role doctoral trainees play in the nation’s engineering and STEM enterprise” and noted several of the foundation’s awards and programs that support graduate research.

Funding shocks may also force Pennsylvania State University to reshape future admissions decisions, according to Madhavan Swaminathan, head of Penn State’s electrical engineering department and director of the Center for Heterogeneous Integration of Micro Electronic Systems (CHIMES), a semiconductor research lab.

In 2023, the Defense Advanced Research Projects Agency (DARPA) and industry partners awarded CHIMES a five-year $32.7 million grant. But in late 2025, the agency pulled its final year of funding from the center, citing a shift in priorities from microelectronics to photonics, Swaminathan says. As a result, CHIMES’ annual budget, which supports research assistantships for roughly 100 engineering graduate students, the majority pursuing Ph.D.s, will fall from $7 million in 2026 to $3.5 million in 2027. If these constraints persist, Penn State’s engineering department may reduce the number of doctoral students it supports.

In a statement, a DARPA spokesperson told IEEE Spectrum: “Basic research is central to identifying world-changing technologies, and DARPA remains committed to engaging academic institutions in our program research. By design, a DARPA program typically lasts about 3 to 5 years. Once we establish proof of concept, we transition the technology for further development and turn our attention to other challenging areas of research.”

Penn State’s enrollment numbers reflect Swaminathan’s caution. He says the electrical engineering Ph.D. cohort shrank from 28 students in 2024 to 15 students in 2025. Applications show a similar pattern. After rising from 195 in 2024 to 247 in 2025, Ph.D. applications fell roughly 30 percent to 174 for the upcoming 2026 cohort, a sign that prospective students may be wary of applying to U.S. programs.

Immigration restrictions and application declines

In late January, the Trump administration announced it had paused visa approvals for citizens of 75 countries. Months earlier, the administration proposed new restrictions on student visas, including a four-year cap.

For Texas A&M University’s graduate electrical and computer engineering programs, up to 80 percent of applicants each year are international students, according to Narasimha Annapareddy, professor and head of the department. Annapareddy says applications for the fall 2026 Ph.D. cohort have dropped by roughly 50 percent.

Annapareddy says the United States is “sending a message that migration is going to be more difficult in the future.” Foreign students often pursue degrees in the U.S. not only for academic training, he says, but to build long-term careers and lives in the country. Fewer applications from international students mean that the university forgoes a “driven and hungry” segment of the applicant pool who are highly qualified in technical fields.

At the University of Southern California, the decline is more moderate. The freshman Ph.D. class fell from about 90 students in 2024 to roughly 70 in 2025, a reduction of 22 percent, according to Richard Leahy, department chair of USC’s Ming Hsieh Department of Electrical and Computer Engineering.

While Leahy says applications are down modestly overall, domestic applications have increased by roughly 15 percent. Beyond immigration restrictions, international students, particularly from countries such as India and China, may be staying in their home countries as their technology sectors expand.

“A lot of those students that would normally have come to the U.S. are now taking very good jobs working in the AI industry and other areas,” Leahy says. “There are a lot more opportunities now.”

Workforce pipeline strains

Some faculty say shrinking cohorts could erode the tech workforce if the pattern continues.

At UC Los Angeles, Iyer describes a doctoral ecosystem built on a chain of mentorship. Among the roughly 25 students in his lab, senior doctoral students mentor junior Ph.D. candidates, who in turn guide master’s students and undergraduates. The system depends on overlapping cohorts. Reducing the number of students hired weakens that overlap and the trickle-down benefits of the mentorship model that keeps labs functioning.

The real benefit of the university system isn’t just the teaching but also “the community that you build,” Iyer says. “As you decrease admissions, this will disappear.”

At Penn State, Swaminathan points to specialization as key to a strong workforce. Many doctoral students train in semiconductor engineering, feeding expert talent into the domestic chip industry. If enrollment continues to shrink over the next few years, Swaminathan says, companies may need to hire students with bachelor’s or master’s degrees, who might lack the necessary skills required to design and innovate new chips.

“Without that specialization, there’s only so much one can do,” Swaminathan says.

The industry–academia gap

Not all departments are shrinking. At the University of Texas at Austin, overall enrollment has remained relatively steady, according to Diana Marculescu, chair of UT Austin’s Chandra Family Department of Electrical and Computer Engineering.

While she says recent fluctuations aren’t raising alarms, her concern lies more with alignment between research and industry. Doctoral students often train according to current grant priorities, she says. But by the time graduates enter the job market four to six years later, their specialization may not align neatly with open roles. That creates friction in the talent pipeline.

“That lack of connection might be problematic,” Marculescu says. She argues that closer collaboration between universities and the private sector could help create stronger feedback loops between hiring needs and academic research priorities.

For now, USC’s Leahy says Ph.D. graduates remain in high demand, and the current shifts have not yet translated into measurable workforce shortages. “We should be concerned about the number of Ph.D.s,” he says. “But there isn’t a crisis at this point.”
