Become a Fellow

* Applications for the 2024 cohort of the Horizon Fellowship are open until September 15th. Submit your application here. *

Through our flagship Horizon Fellowship, we place fully-funded fellows at host organizations to help tackle policy challenges related to artificial intelligence, biotechnology, and other emerging technologies.


Fellows selected for our program receive policy-focused training, mentorship, and support in matching with a host organization for a full-time, fully-funded fellowship based in the Washington, DC area. Potential host organizations include executive branch offices, congressional offices, and think tanks.​

What you get from the fellowship

As a Horizon fellow, you would receive:


  • Dedicated training on the policy landscape and applied skills such as writing and policy analysis

  • Access to a tight-knit fellowship community of supportive peers with similar interests

  • Introductions to many possible host offices central to US AI and biosecurity policy

  • Support from senior mentors and the broader Horizon community, both before and during your placement

  • Competitive financial support during your fellowship placement


Fellows are selected for a one-year term at a federal agency, congressional office, or think tank, with the option of renewing for a second one-year term (potentially on a different institutional track). Junior think tank fellows are selected for a six-month term and can renew for a second six-month term. Fellows receive a $105,000/year living stipend and junior fellows $70,000/year; both also have access to more than $20,000 worth of benefits such as health care and professional development stipends. Increases may be considered on the basis of need (see our FAQ for more details).

Fellowship tracks and eligibility

Fellows complete placements at federal agencies, congressional offices, and think tanks

Check out our list of past fellows for examples of placements in each of these three categories. The eligibility guidelines below are deliberately somewhat broad. If you’re not sure whether you are eligible or qualified, we strongly encourage you to still apply. We care more about attitude and aptitudes than formal credentials.

Federal agencies craft, implement, and enforce policy and law. Executive branch fellows will support their host agency through assistance with technology-related research and analysis, writing and editing policy documents, coordinating work within and across agencies, briefing colleagues, and staffing leaders. Executive branch fellows are expected to have strong subject-matter expertise, excellent communications skills, and an ability to manage social and organizational dynamics within and between federal offices.

Federal agencies

Congress passes laws and oversees the executive branch. Congressional fellows may work in a Member's personal office or on the staff of a committee. They will be involved in activities such as researching technology-related policy topics, briefing members and colleagues on emerging technology issues, drafting legislation, and building coalitions. Successful congressional fellows will enjoy working in a fast-paced, collaborative, and politically complex environment, and be good at juggling a relatively broad portfolio of policy issues.

Congressional offices

We expect competitive applicants for the executive branch or congressional tracks to have the following qualifications:

  • Several years of professional experience

  • Ability to communicate complex ideas to non-technical policy audiences (both in writing and verbally)

  • A credential (e.g. work experience, degree, publications, or similar) related to area of focus

  • Strong interpersonal, writing, and verbal communication skills

  • Ability to build coalitions and navigate social and political complexity

  • A graduate degree (not required; strongly preferred for executive branch fellows)

Think tanks inform US policymakers through research and analysis. Think tank fellows will support emerging technology-related work within existing think tank programs. Junior fellows’ work will likely involve a combination of research assistance on existing projects, writing short-form content, organizing events and workshops, and other project and communications support. More experienced fellows could lead policy research projects, brief policymakers, and publish articles and reports. Successful think tank fellows are likely to have strong research, writing, and project management skills.

Think tanks

We expect competitive applicants for the think tank track to have the following qualifications:

  • Several years of research and writing experience (academic or professional)

  • A credential (e.g. work experience, degree, publications, or similar) related to area of focus

  • Strong analytic and writing skills, and a demonstrated ability to bring projects to completion independently

  • Ability to communicate complex ideas to non-technical policy audiences 

  • A PhD or other terminal degree (not required; strongly preferred)

​​We expect competitive applicants for the think tank junior fellow track to have the following qualifications:

  • Recently obtained a bachelor’s or master’s degree (including those graduating in the year that their placements would start, e.g. those who apply in September 2023 may graduate in spring 2024)

  • Demonstrated interest in AI, biosecurity, or related emerging technology areas

  • Strong analytic, writing, project management, and communications skills

  • Prior experience with research and/or project management (not required; preferred)

General eligibility

All fellows must be eligible to work in the United States and willing to live in the Washington, DC area for the duration of their placement. We are not able to sponsor US employment visas for fellows; US permanent residents (green card holders) are eligible to apply, but fellows who are not US citizens may be ineligible for placements that require a security clearance.* International students on an F-1 visa may be eligible for the think tank track during their first year of post-graduation OPT (we cannot accommodate STEM OPT).

We strongly encourage individuals with backgrounds and experiences underrepresented in science and technology policy to apply, such as women, veterans, and people of color.

If you have further questions about eligibility, please consult our fellowship FAQ.


* Security clearance requirements are most common for executive branch placements, for example those at national security-focused departments and agencies. Permanent residents are able to work in most Congressional offices and think tanks, and may also be eligible for certain executive branch placements.

Application process

We are accepting applications for the 2024 cohort until September 15th. You can apply here.

Our initial application form asks for the following items:

  • A CV or resume (≤ 2 pages)

  • Most recent college or university transcript (optional for applicants with 5+ years of work experience)

  • A series of short answer questions on your motivations and experiences (≤ 200 words) 


After the initial submission, successful applicants will go through a series of interviews and one short work test. We are committed to using evidence-based best practices in our application and review process to promote diversity within our talent pool, such as blind-grading application materials and compensating applicants for their time spent on work tests. More information about our process can be found in our fellowship FAQ.

Potential applicants can also register interest here to information sessions happening on August 22nd and 28th, during which you can ask questions about the program and the application process.

Program stages and timeline

  • 1. Training
    Successful applicants go through a training program that prepares them to secure high-impact placement offers and to perform high-quality work during their fellowship. The training focuses on (a) improving policy-relevant skills such as writing, communication, and analysis; (b) providing background on relevant government institutions and policy stakeholders; and (c) helping finalists identify promising potential host organizations and offices. Think tank and executive branch track participants have 10 weeks of part-time training. This involves 2-3 weekday evening sessions, a remote weekend around the start of the training period, and an immersive in-person weekend in DC at the end of the training period. Outside of the two weekends of programming, participation requires approximately 8 hours of remote work per week (including policy memo writing, readings, virtual talks, and interactive sessions). The schedule is designed to allow participants to continue a full-time job or degree during training. Congressional track participants receive training in collaboration with an institutional partner and follow a slightly different training and placement schedule. They participate in three weeks of full-time training in Washington, DC in either January or June. As they have to be available full-time and relocate to participate in the training program, they receive compensation starting during the training period. While we cannot guarantee a placement, our institutional partner has historically placed every one of the many dozens of people that have gone through their training.
  • 2. Matching
    After participants complete their training, they receive extensive one-on-one support in matching with a host organization. The ultimate responsibility for finding and being accepted by a host organization rests with the finalist; if finalists fail to secure a placement within the matching period, they will exit the program. While we cannot guarantee a placement, we expect an overwhelming majority of the finalists to be able to secure fellowship placements. All 35 finalists in our prior two cohorts secured a placement (100% placement rate). Participants in the think tank and executive branch tracks are required to find a host organization within two months of completing the training. This search process can be done remotely, allowing participants to continue their jobs or degree programs until they have secured a placement. While we require participants to be accepted by a host organization within two months, their actual start date is determined on a case-by-case basis and may fall outside of this window (see below). The matching period for participants in the congressional track lasts three weeks, so fellows who trained in January choose their placements in February. As they already relocated to DC for training, matching activities and interviews with prospective host offices typically take place in person (circumstances permitting). Congressional track participants are compensated during the matching period and expected to start their placement as soon as possible after finding a host office. Matching support includes a series of one-on-one conversations to identify potential host organizations that fit applicants’ skills and interests, support from experienced advisors, introductions to current and former employees of prospective host organizations for exploratory conversations, and feedback on application materials (e.g. writing samples) and interview coaching. Once applicants have created their shortlist of potential host organizations, we facilitate introductions to the relevant hiring managers. We also support applicants in navigating host organizations’ administrative requirements.
  • 3. Placement
    Once they have secured a host organization, applicants officially become “fellows” and work full-time at their host organization in the Washington, DC area for the duration of their fellowship. During their placement periods, fellows also receive tailored professional development content and extensive one-on-one mentorship and career support. The fellowship cohort meets regularly, both with each other and with senior policy leaders, to build community and learn about different aspects of policy work. Start date. Congressional fellows are expected to start their placements as soon as possible after they have found a host office. Exact start dates for executive branch and think tank fellowship placements will be determined on a case-by-case basis in consultation with each fellow and host organization, but are expected to be in the spring or summer of the year they were selected for. Compensation. As of 2023, the standard fellowship stipend is $70,000 per year for junior fellows and $105,000 for congressional, think tank, and executive branch fellows. Increases may be considered if financial necessity would otherwise preclude a fellow from participating in the program. Additionally, fellows receive around $10,000 post-tax per year to support health insurance and health expenses, $3,000 for relocation to Washington DC (if needed), and up to $3,000 per year for professional development activities. Duration and renewal. Initial placement terms are 6 months for junior fellows at think tanks and 12 months for the other three fellowship tracks. Fellowship renewal is possible by mutual agreement between Horizon, the fellow, and a host organization. We expect to renew most fellows, except in cases of poor performance or lack of investment in the Horizon community. Total fellowship duration could therefore be up to 12 months for junior fellows and 24 months for the other fellows. Fellows can do their second 12-month term on a different placement track, so that they can for instance do their first year at a think tank and second year in Congress (this does not apply to think tank junior fellows because they are only eligible to place in think tanks).

The program consists of three stages:
