Whether naturally occurring, accidental, or deliberate, biological threats require a unified government response. The US executive branch designs and implements programs to prevent, prepare for, and respond to biological threats—from developing vaccines and diagnostic tests to monitoring disease outbreaks, ensuring the safe development of biotechnology, and preparing communities for emergencies. These efforts are shaped by Congress, presidential directives, court decisions, and expert input from organizations outside government, like think tanks.

If you’re looking to explore or advance a career in biosecurity policy, you’ll find opportunities across nearly every executive department and agency. Understanding how these government components work to counter biological threats is essential for choosing where to work and for finding policy opportunities to improve our preparedness. This guide will help you understand the big picture:

  • What “biosecurity” means and why the definition matters
  • How different agencies approach biological threats
  • Which agencies handle prevention, detection, and response
  • How agencies coordinate on biosecurity initiatives (with real-world examples)
  • And tips on pursuing executive branch biosecurity careers

Our further reading section includes more in-depth resources, including national strategies and think tank reports, which review US government biosecurity efforts.

What is “biosecurity”?

This website offers resources for those interested in biosecurity, which we understand broadly as all efforts to prevent, prepare for, and respond to biological threats. This field overlaps with several related areas—global health security, biosafety, and biodefense—with different DC communities using these terms in distinct ways that reflect their professional perspectives and priorities—something worth noting when building relationships across government.

In government contexts, key terms to help navigate biosecurity policy discussions include:

  • Biosecurity focuses on protecting human health, food systems, and ecosystems from biological threats. This includes preventing the spread of harmful organisms (from viruses to invasive species) and stopping the intentional misuse of biological materials.1
  • Global health security emphasizes building strong public health systems worldwide to handle disease outbreaks and health emergencies. You’ll often hear this term in international development and diplomatic circles, where the focus is on helping countries work together to stop threats before they spread.
  • Biosafety centers on laboratory safety practices to prevent accidental exposure to dangerous biological materials. This term is common among lab scientists, safety officers, and regulators who work to protect researchers and their communities.
  • Biodefense typically refers to protecting against deliberate biological threats like bioterrorism. You’ll hear this most often in national security and defense circles, though some use it more broadly.2

Mapping the federal biosecurity ecosystem

If you’re unsure which department, agency, or office aligns with your interests, focus on understanding how they specialize and fit into big-picture biosecurity work. But also keep in mind that an office’s responsibilities may include less publicly visible or classified work and can shift based on new priorities, funding, and political leadership.

To navigate this complex landscape, it’s helpful to understand the operational dimensions that shape how government agencies approach biosecurity work—ranging from policy development to implementation, domestic to international focus, or crisis response to prevention. Recognizing where an agency or office falls along these dimensions can clarify its role in biosecurity and help you identify agency opportunities matching your skills and interests. The examples below illustrate how some specific agencies and their subdivisions operate along these dimensions, though many work across multiple areas simultaneously. Note that the specific roles and responsibilities in the examples below may change across administrations; focus instead on the differences they illustrate.

What agencies work on in biosecurity

Building on the operational dimensions above, we can also understand the executive branch’s biosecurity work by considering the core functions of biological threat prevention, detection, and response. Below is a mapping of how different departments and agencies contribute to each area, though many work across multiple domains and this overview may not capture every agency’s complex and multifaceted contributions. Our agency profiles (linked throughout this section) provide more in-depth information on the subagencies and offices contributing to these topics.

COVID-19 vaccines as a case study in government coordination

The rapid development and distribution of COVID-19 vaccines is one of the most compelling illustrations of coordinated government biosecurity efforts. This historic collaboration underscores the importance of each agency leveraging its unique authorities, resources, and capabilities across the different operational dimensions and functions discussed above. 

Major government initiatives typically involve many agencies, making it valuable to understand their roles, responsibilities, cultures, and potential conflicts. Some agencies generally have more influence over specific policy issues—for instance, while many agencies contributed to COVID-19 vaccine development and distribution, the Food and Drug Administration (FDA) had the final authority to approve vaccines.

As this guide shows, biosecurity work in the executive branch offers diverse career opportunities, from strategy development to research to emergency response. Encompassing hundreds of distinct agencies, the executive branch collectively employs millions of people and offers job opportunities year-round—including many relevant to biosecurity.

To complement this general overview of executive branch biosecurity policy work, explore our agency profiles for deeper dives into the office structures, recent biosecurity initiatives, and employment pathways at specific agencies. Our researching federal agencies guide further explains how you can conduct your own research on agencies and offices aligned with your policy interests. 

Understanding the basics of federal employment is essential for pursuing agency roles. Our federal agency application advice includes resources on interviewing for federal positions, understanding USAJOBS.gov (the official website for federal jobs), and federal resume advice. Positions relevant to national security also generally require a security clearance, which can take months or more than a year. 

Our guide on building professional networks in DC and our bio policy resources list can also support your journey into bio policy work. For entry pathways, virtually all agencies involved in bio policy offer internships, and many provide fellowship opportunities for early- to mid-career individuals.

Here are some key takeaways if you’d like to work in this space:

  • Different agencies approach biosecurity in distinct ways. Some focus on policy development while others handle day-to-day operations; some work domestically while others engage internationally; some concentrate on prevention while others specialize in response. The scope of work is remarkably diverse, encompassing research, analysis, coordination, project management, communications, software development, and more. Consider which of these approaches align best with your skills and interests.
  • There are opportunities for people from diverse backgrounds to contribute meaningfully to biosecurity. While medical or life science experience can be valuable and may be required for certain roles, many positions need expertise in areas like policy analysis, law, economics, ethics, or communications. Your background—whether in financial analysis, communications, or data science—can be valuable in developing and implementing biosecurity policy.
    • What’s more, agency staffers often have experience working in Congress and organizations outside government like think tanks, and many move between these different institutions throughout their careers. This career mobility allows you to build relevant experience, networks, and expertise from multiple angles.
    • So, when you’re just starting out, don’t restrict your search just to agency opportunities with “biosecurity” in the title—you should cast a wide net across different policy areas and institutions. For example, you can look for biosecurity-adjacent positions in think tanks or Congress related to public health, science or technology policy, international diplomacy, or national security. Getting your first position is often the hardest, but fortunately (given the highly transferable knowledge and skills), you can typically move laterally between policy roles regardless of where you begin your career.
  • Each agency controls different policy levers for biosecurity. For example, if you’re passionate about the safe conduct of life sciences research, you might focus on agencies that regulate laboratory safety (CDC), fund and oversee research grants (NIH), or engage internationally on research oversight (State). Offices with strong coordination roles—typically in or near the White House—can provide particularly valuable overviews of how different parts of government work together to achieve cross-cutting initiatives.
