ALS Collaborative Postdoctoral Fellowship Spring 2027: $36,500 Stipend for Synchrotron Research at Berkeley Lab

ALS Collaborative Postdoctoral Fellowship Spring 2027: $36,500 Stipend for Synchrotron Research at Berkeley Lab

The Advanced Light Source (ALS) Collaborative Postdoctoral Fellowship is a specialized research opportunity for scientists and engineers whose work will benefit from the capabilities of a major synchrotron facility. The spring 2027 cohort places fellows at the ALS, part of Lawrence Berkeley National Laboratory, where they work on a defined collaborative project with ALS staff, an external postdoctoral advisor, and potentially other users of the facility.

Applications open on September 8, 2026 and close on October 2, 2026, at 11:59 p.m. Pacific Daylight Time. The planned fellowship start date is April 1, 2027, although the ALS says applicants may propose an earlier start as soon as February 1, 2027. A normal fellowship lasts one year, ending March 31, 2028, but applicants may request a shorter term of at least six months when the proposed timing makes sense for the research and the facility schedule.

The financial support is a $36,500 annual stipend, paid directly to the fellow in monthly installments. This is a fellowship stipend rather than a salary, and it does not include benefits. Fellows must therefore arrange a source of collaborative funding and benefits, usually through an external postdoctoral fellowship or a collaborating advisor outside the ALS. Researchers whose home institution is outside the United States may also receive a one-time $3,000 stipend payment for additional costs of temporarily relocating to and residing in the United States.

This is not a general postdoctoral scholarship and it is not a Lawrence Berkeley National Laboratory employment offer. The strongest applicants will already have a clear research direction, a plausible reason to use ALS tools, a potential ALS staff collaborator, and an institutional arrangement that covers benefits. For that audience, the program combines financial support with access to staff expertise, beamlines, instruments, and a concentrated research environment.

Key details

The ALS page is the controlling source for the fall 2026 application cycle. The facility is undergoing changes connected with the ALS-U upgrade, so applicants should check the official page again when the application form opens and discuss proposed dates with a prospective host.

What the fellowship provides

The principal benefit is a year in residence at a facility built around advanced synchrotron radiation tools. ALS fellows pursue collaborative research and instrument development in areas that support the scientific missions of the Department of Energy, Berkeley Lab, and the ALS. The facility describes the fellowship as an opportunity to work with ALS staff and members of its user community on scientific challenges that can be tackled with the available instrumentation.

That setting can be especially valuable when a project needs more than occasional access to a beamline. A fellow can develop a working relationship with scientific and engineering staff, learn how to plan experiments around facility constraints, and refine methods in conversation with researchers who support many different applications. The official program page does not restrict applications to one named field. It instead asks applicants to show that their research will benefit from ALS capabilities and that the proposed collaboration fits the facility’s research needs.

The program also includes professional development. The ALS lists an orientation program, seminars during the year, and an opportunity to present results at the end of the fellowship. These activities give the fellow a structured way to explain the work, receive feedback, and build connections across the facility. The fellowship is therefore useful for someone who wants both research access and experience communicating a project to a multidisciplinary scientific audience.

The stipend is flexible in the sense that it is paid directly to the fellow and may help cover room and board, travel, research, clerical help, or equipment. It is not a salary and does not automatically provide health insurance, retirement contributions, or other employee benefits. The requirement for a separate source of benefits is one of the most important financial details in the entire opportunity. Applicants should confirm exactly what their home institution, external funder, or collaborating advisor will cover before treating the $36,500 as a complete funding package.

Who this opportunity fits

The program is aimed at researchers who have completed a doctoral research degree from an accredited academic institution in an appropriate scientific or engineering discipline. Applicants must have fewer than five years of postdoctoral experience on the date the fellowship ends. A researcher whose experience is close to that limit should calculate the timing carefully rather than assume that a general early-career label is enough.

Applicants must be legally eligible to work in the United States, regardless of citizenship. This wording means citizenship alone is not the deciding factor, but authorization is still required. International researchers should begin discussions about their status and institutional arrangements early because the fellowship does not itself promise an immigration outcome.

The research must benefit from ALS capabilities. A broad statement that a project is related to materials, chemistry, physics, energy, biology, or another facility-relevant area is not enough by itself. The application should identify the measurement, instrument, beamline expertise, or experimental environment that makes the ALS a meaningful part of the project. The prospective fellow should also show why the proposed work is collaborative rather than simply a project that happens to be located in Berkeley.

Applicants need a source of collaborative funding and benefits for the fellowship duration. The ALS says this is usually provided by a collaborating postdoctoral advisor outside the ALS or by an external postdoctoral fellowship. The arrangement must be credible before the fellowship starts. The page also says proof of Ph.D. completion and collaborative postdoctoral support, such as a signed appointment offer from the home institution, must be provided at least one month before the fellowship begins.

Lawrence Berkeley National Laboratory employees and postdocs are not eligible to participate in the ALS Fellowship Program. Applicants should also note the residence expectation: fellows must live in or near Berkeley and be on site at Berkeley Lab at least 70% of the time. That makes the program a poor fit for a project that can be completed remotely or for a researcher who cannot relocate for a substantial part of the term.

Find an ALS collaborator before applying

The ALS specifically advises prospective applicants to contact one or more ALS staff members to discuss common research interests and agree on a potential project and scope. This should happen before the application is drafted in its final form. The staff directory and beamline information linked from the official page are useful starting points, but a list of names is not a collaboration plan.

An effective first conversation can be short and concrete. Explain the research question, the current stage of the work, the measurement or capability you need, and what you hope to accomplish during the proposed residence. Ask whether the idea fits the relevant ALS program or beamline, what practical constraints should shape the scope, and whether the staff member would be able to provide the required host letter. The goal is not to pressure a scientist into sponsoring a vague project. It is to test the research fit early enough to revise the proposal.

The host relationship matters because the application asks for a letter from the ALS host describing how the project would benefit from ALS capabilities and advance ALS programs and strategic directions. A generic endorsement that only praises the applicant will not answer that question. The host should be able to explain the technical collaboration, the available environment, and why the proposed work is feasible during the requested dates.

Application materials and process

The application form asks for a current curriculum vitae and publication list, a statement of the research to be performed of up to two pages, and a statement of up to one page explaining how being in residence at the ALS and Berkeley Lab will benefit the research and career development. Applicants must also provide proof of the Ph.D.; the official page notes that this proof is required at least one month before the fellowship start date.

Supporting letters are submitted separately through the same application process. The published requirements include a recommendation from the postdoctoral supervisor endorsing the collaborative research project, a letter of institutional support from the home institution or funding agency, and a letter from the ALS host. These letters serve different purposes. The supervisor addresses the applicant’s research preparation and the project’s value. The institution or funder confirms the collaborative support and benefits arrangement. The ALS host explains facility fit and the practical research collaboration.

The fall 2026 cycle opens September 8 and closes October 2 at 11:59 p.m. PDT. The page does not state a separate earlier deadline for each letter, so applicants should not infer that referees can submit after the main closing time. Ask letter writers to complete their portions before the final day and monitor the application system for missing materials.

After submission, applications are reviewed by a panel of ALS scientists and leadership. The published evaluation factors are the applicant’s qualifications, the merits of the proposed collaborative research, and alignment with ALS programs and strategic priorities. Successful applicants are expected to begin around April 1, 2027, unless an alternate date is approved.

How to build a convincing research statement

Start with the scientific problem, then connect it to the facility. The first page should make clear what is not yet known, why the gap matters, and what evidence would change understanding in the field. The next step is the ALS case: identify the exact capability that makes the proposed research possible, more reliable, or meaningfully more ambitious than the work could be without the facility.

Keep the project appropriately sized for the requested residency. A proposal that promises an entire research program, several unrelated sample systems, and a complete publication pipeline may look ambitious but can be less credible than a focused sequence of experiments. State the first experiment, the decision it will inform, the likely follow-up, and the result that would count as progress. Include enough technical detail for a specialist reviewer to judge feasibility, while explaining abbreviations and field-specific assumptions for ALS leaders who may not work in the same subfield.

The residency statement should not repeat the research summary. Explain what changes because the fellow will be at Berkeley Lab. Discuss access to staff expertise, instruments, facilities, and the user community, along with the skills the applicant expects to develop. Tie the residence plan to the project’s milestones. If the proposed fellowship is shorter than a year or begins before April 1, explain the operational or scientific reason, as the ALS requests justification for alternate dates.

Evidence quality matters. Use the publication list to show preparation for the proposed work, but do not make reviewers reconstruct the connection themselves. Point to the methods, datasets, experiments, or technical contributions that demonstrate readiness. If the project builds on doctoral work, state what is established and what the fellowship would add. If the applicant has limited synchrotron experience, explain the adjacent expertise and the training or collaboration that closes the gap.

Financial and logistical planning

Treat the $36,500 as an annual stipend, not as an employee salary. Because the program says the stipend does not include benefits, obtain written confirmation of the benefit source before accepting an award. Ask the home institution or external funder how coverage works while the fellow is physically in the United States and whether any conditions apply to the appointment.

Budget for Berkeley housing, local transportation, food, research-related costs, and any travel that the stipend may need to cover. The additional $3,000 payment for fellows from non-U.S. home institutions is helpful, but it is a one-time amount for extra relocation expenses, not a guarantee that all international travel, visa, housing deposit, or tax costs will be reimbursed. The official page does not publish a detailed tax treatment, so applicants should consult their institution or a qualified adviser rather than assume the stipend is tax-free.

The 70% on-site requirement also needs a real plan. Identify where the fellow will live, how often travel away from Berkeley may be necessary, and how experiments, seminars, and collaboration will be handled. A remote-work assumption could conflict with the appointment terms. International applicants should also confirm authorization and timing early, especially if the planned start date is moved forward to February.

Common mistakes to avoid

The most serious mistake is applying without a credible facility match. The ALS is not simply offering a paid place to write papers. The project must benefit from ALS capabilities, and the host letter must describe that benefit. Contact staff before submission and narrow the project if the proposed work does not need the facility.

Another mistake is ignoring the separate benefits requirement. An applicant can meet the degree and publication expectations and still be unable to take up the fellowship if the collaborative funding and benefits arrangement is missing. Confirm that support before the deadline, not after an award notice.

Do not describe the stipend as a salary or imply that it includes employee benefits. The official program expressly distinguishes the fellowship from an employee position. Similarly, do not present the $3,000 relocation payment as full international relocation coverage.

Avoid submitting a generic two-page proposal that could be sent to any laboratory. Explain the ALS capability, the collaboration, the work plan, and the reason the on-site environment matters. Finally, do not leave letters until the last hours. Three different supporting documents are required, and each one must establish a different part of the application’s case.

Frequently asked questions

Is this an employee position at Berkeley Lab?
No. The ALS says the stipend does not constitute a salary and that the fellowship is not an employee position. Benefits are not included, and applicants must have collaborative funding and benefits for the duration.

How much funding is confirmed?
The annual stipend is $36,500 and is paid directly to the fellow in monthly increments. Fellows from non-U.S. home institutions may receive a one-time $3,000 relocation stipend. The official page does not describe the relocation payment as full cost reimbursement.

Can a researcher apply without U.S. citizenship?
Yes, the eligibility language is based on legal eligibility to work in the United States regardless of citizenship. International applicants must still arrange the required authorization and institutional support.

Can the fellowship be shorter than one year?
Yes. The ALS says applicants may request a shorter fellowship of at least six months, with the stipend prorated. The applicant should discuss the dates with the prospective host and justify the alternative timing in the residency statement.

What is the expected start date?
The next cohort is scheduled to begin April 1, 2027. Applicants may propose an alternative start as early as February 1, 2027, subject to the program’s review and operational needs.

What should a prospective applicant do first?
Read the official program page, identify an ALS staff member whose research is a genuine match, and discuss the project scope and dates. At the same time, confirm the external or home-institution source of benefits and collaborative support.

Official links and next steps

Start with the official ALS Collaborative Postdoctoral Fellowship page. It contains the current dates, eligibility requirements, award terms, application materials, staff and beamline links, evaluation criteria, and contact information for Ashley White, ALS Division Deputy for Strategy.

Before September 8, prepare a current CV and publication list, a concise research concept, a one-page residence plan, and a list of potential ALS collaborators. Confirm that you will meet the doctoral-degree and postdoctoral-experience limits by March 31, 2028. Ask your postdoctoral supervisor and home institution or funder whether they can provide the required letters and benefits support. Once the form opens, verify the live instructions and submit before October 2 at 11:59 p.m. PDT.

This fellowship is worth pursuing when the ALS is part of the research logic, not merely the location. A focused project, a prepared host relationship, and a confirmed benefits arrangement will do more for the application than a broad promise to use advanced instruments. For the right postdoctoral researcher, the award provides a year of facility-based collaboration, direct financial support, and professional development in one of the most capable synchrotron research environments in the United States.
