What It Means for Science's Future
The National Institutes of Health, America's premier biomedical research agency with a $45 billion annual budget, is undergoing its most significant transformation in decades. Rather than announcing new appointments to its prestigious Advisory Committee to the Director (ACD), the current administration has taken the unprecedented step of dismissing all existing members and restructuring its advisory framework 6 9 . This sweeping change represents a fundamental shift in how scientific governance will operate at the highest levels of medical research. The dissolution of multiple advisory committees raises critical questions about how emerging technologies will be overseen and which voices will guide future research priorities at the world's largest public funder of biomedical science.

ACD Members Dismissed
ACD Establishment Year
In July 2025, NIH Director Dr. Jay Bhattacharya dismissed all 10 members of the Advisory Committee to the Director (ACD), marking what appears to be the first "clean sweep" in the committee's history dating back to 1966 6 9 . The ACD has traditionally served as a crucial resource for NIH directors, providing recommendations on issues ranging from artificial intelligence in research to revitalizing postdoctoral training programs 6 .
Simultaneously, the agency is sunsetting specialized committees like NExTRAC (Novel and Exceptional Technology and Research Advisory Committee), which was established in 2019 to provide oversight on emerging biotechnologies 4 8 . This committee had just completed a comprehensive two-year roadmap to increase community engagement in NIH-funded science when members received termination notices in May 2025 4 .
The administration justifies these changes as necessary to "make the NIH run more efficiently" and streamline operations 4 8 . However, many in the scientific community express concern about losing diverse expertise and patient perspectives that these committees provided 4 .
The timing appears particularly contradictory regarding NExTRAC, which was terminated immediately after presenting a community engagement roadmap that Director Bhattacharya praised for addressing his stated priority of "rebuilding public trust in clinical research" 4 8 . This disconnect has left many panelists and observers confused about the strategic direction of the agency 8 .
To understand the potential consequences of these changes, we can examine the traditional functions of NIH advisory committees through three key metrics:
Advisory councils serve as the second stage of NIH's peer review process, making final checks on applications before funding decisions 6 9 .
Committees like NExTRAC evaluated groundbreaking technologies such as CRISPR gene drives and novel uses of personal health data 8 .
Advisory groups produced comprehensive reports on priority issues, such as the community engagement roadmap NExTRAC delivered just before its termination 4 .
The changes have already produced measurable effects across multiple dimensions of NIH operations:
| Area of Impact | Documented Consequence |
|---|---|
| Grant Review Capacity | Dozens of scientists dismissed from advisory councils, leaving them "very understaffed" 9 |
| Emerging Tech Oversight | No clear mechanism to replace NExTRAC's role in evaluating novel biotechnologies 4 8 |
| Expertise Diversity | Loss of patient advocates and community perspectives in research design 4 |
| Administrative Burden | Staff screening candidates' social media for political alignment 9 |
Timeline Impact: The process of replacing committee members requires significant time and resources, traditionally taking "2 years for NIH staff to screen candidates, nominate them, get them approved by NIH and HHS, guide them through background and ethics checks, and train them for the role" 9 .
The current restructuring must be understood within the historical context of NIH advisory committees and their crucial role in American science. The recently terminated NExTRAC committee continued the work of the storied Recombinant DNA Advisory Committee (RAC), which began in the mid-1970s 4 . RAC's historical impact includes:
Overseeing the development of synthetic insulin, which revolutionized diabetes treatment 8
Guiding gene therapy through its challenging early clinical trials 8
Establishing safety frameworks that enabled today's successful gene therapy applications 8
Creating ethical guidelines that became international standards 8
This historical perspective highlights what might be lost when such committees are disbanded without clear replacements. As one report noted, RAC's work during gene therapy's "rocky entrance" into clinical testing proved invaluable in transforming experimental procedures into proven medical treatments 8 .
Advisory committees serve as essential components of the scientific infrastructure, each with specific functions and responsibilities. The recent changes have affected multiple types of committees:
| Committee Type | Primary Function | Current Status |
|---|---|---|
| Advisory Committee to the Director (ACD) | Advises NIH director on program development, resource allocation, and policy | All members dismissed; to be reconvened with new leadership 5 9 |
| Institute Advisory Councils | Second-stage peer review of grant applications; programmatic priority setting | Dozens of scientists dismissed; replacements being sought 2 9 |
| Specialty Advisory Committees | Address emerging technologies and specific ethical challenges | Committees like NExTRAC terminated 4 8 |
| Board Committees | Oversee specific facilities and operations | Continuing operations with published meeting schedules |
The long-term consequences of these structural changes will unfold over years, but several critical areas deserve attention:
With NExTRAC disbanded, significant questions remain about how the NIH will navigate future ethical dilemmas and biosafety concerns posed by rapidly advancing technologies like CRISPR gene editing, AI integration with genetic research, and novel uses of personal health data 8 . These technologies present unprecedented challenges that require multidisciplinary expertise.
The dismissal of dozens of scientists slated to join advisory councils threatens to strain NIH's peer review system 9 . These councils play an essential role in the grant funding pipeline, and understaffing could delay critical research funding decisions across numerous disease areas.
Director Bhattacharya's stated priority of "rebuilding public trust in clinical research" may be complicated by eliminating committees specifically focused on community engagement and transparency 4 8 . This creates a potential paradox where the solution to distrust might involve reducing community input mechanisms.
The sweeping changes to NIH's advisory structure represent a significant experiment in scientific governance. While efficiency improvements may be necessary and welcome, the scientific community and public must remain vigilant to ensure that crucial advisory functions aren't diminished in the process. The historical legacy of committees like RAC demonstrates how thoughtful oversight can enable responsible innovation while protecting public safety 8 .
As biotechnology continues advancing at unprecedented rates, the need for diverse expertise and multiple perspectives becomes more critical, not less 8 . The challenge for the NIH leadership lies in determining how to maintain robust oversight while achieving administrative efficiency—a balance that will shape the future of American biomedical research for decades to come.
The coming months will reveal whether the restructured advisory system can adequately address complex issues like artificial intelligence in research, community engagement, and emerging biotechnologies that affect the entire research ecosystem. What remains clear is that how the NIH incorporates external expertise ultimately shapes which diseases get studied, which technologies get developed, and whose health priorities receive attention.
