The California Institute of Technology (Caltech) is renowned for its world-class research and innovation. One of its most prestigious programs for undergraduate students is the Summer Undergraduate Research Fellowships (SURF) Program, a fully funded research opportunity that allows students to gain hands-on experience working at the forefront of science, engineering, and technology. Since its inception in 1979, the SURF program has been a “crown jewel” at Caltech, enabling students to collaborate with experienced mentors and contribute to meaningful research projects.
If you are an undergraduate student passionate about scientific research and looking for an immersive summer experience, the SURF 2026 program could be your gateway to developing essential research skills, building professional networks, and gaining invaluable experience in a highly competitive academic environment.
What is the Caltech SURF Program?
The SURF Program is modeled on the grant-seeking process used by professional researchers. It provides students with an authentic research experience from project conception to presentation. The program includes the following steps:
- Project Proposal: Students collaborate with potential mentors to identify and develop a research project.
- Application Submission: Applicants submit a detailed research proposal as part of the application process.
- Faculty Review: Proposals are reviewed by faculty, who recommend awards based on the strength and feasibility of the projects.
- Summer Research: Selected students work on their projects for 10 weeks during the summer, fully immersed in research.
- Final Presentation: At the end of the program, students submit a technical paper and present their research at SURF Seminar Days, which simulate professional scientific meetings.
This structured approach ensures that students not only contribute to real-world research but also learn essential skills such as proposal writing, technical reporting, and public presentation.
Benefits of Participating in SURF 2026
Financial Support
SURF Fellows receive a fully funded award of $8,110 for the ten-week period, allowing them to focus solely on their research without needing additional employment or coursework.
Professional Development
In addition to hands-on research, SURF provides a series of enrichment activities to develop academic and professional skills:
- Weekly Seminars: Delivered by Caltech faculty and Jet Propulsion Laboratory (JPL) scientists and engineers.
- Workshops on Research Careers: Guidance on graduate school admissions and career planning.
- Effective Communication Training: Learn how to present research clearly and effectively.
- Social and Cultural Activities: Opportunities to network with peers, mentors, and professionals.
- Student-Faculty Dinners: Informal settings to connect with experienced researchers.
These programs are designed to provide students with both technical skills and professional insights to advance their research careers.
Eligibility Requirements for SURF 2026
Caltech Students
To apply as a Caltech undergraduate, students must:
- Be a continuing undergraduate at Caltech.
- Maintain a cumulative GPA of at least 2.0.
- Complete their third term at Caltech or a program approved by a Dean.
- Be eligible for fall term registration before starting the SURF project, no later than July 1.
- Not be under academic or disciplinary sanctions.
Visiting (Non-Caltech) Students
Visiting undergraduate students must:
- Be enrolled in a degree-granting program and eligible for fall term registration.
- Maintain a cumulative GPA of at least 2.5/4.0.
- Complete the second semester or third quarter at their current institution.
- Not be under any academic or disciplinary sanctions.
Special Notes for International Students:
- SURF is open to international students at Caltech, but JPL projects are limited to U.S. citizens and permanent residents.
- International students may need F-1 or J-1 visa authorization and must coordinate with their home institution for CPT, OPT, or Academic Training before beginning their placement.
Expectations of SURF Fellows
SURF participants commit to a rigorous research schedule over the ten-week program:
- Devote full effort to the SURF project (no other courses or jobs allowed).
- Conduct research in person; remote projects are not permitted.
- Submit two interim reports, a project abstract, and a final technical paper approved by their mentor.
- Give a final oral presentation during one of the SURF Seminar Days.
- Adhere to Caltech’s Honor Code and all campus policies.
The program emphasizes intellectual ownership and creativity. Projects should be substantial enough to potentially result in publication in refereed journals.
Application Process
Applying for SURF is a multi-step process designed to simulate real-world research grant applications:
- Identify a Mentor: Students must contact a faculty member in advance. The mentor must agree to supervise the project, help develop the research proposal, and financially contribute to the award.
- Submit Application via SFP Online: The online application includes:
- Research proposal written by the student.
- Two confidential letters of recommendation (one from a faculty member).
- Unofficial transcript (for non-Caltech applicants).
- Faculty Evaluation: Mentors provide confidential evaluations, and faculty review proposals for intellectual merit and feasibility.
Deadline: Applications are due February 22, 2026.
Awards are announced on April 1, 2026.
Writing a Successful SURF Proposal
A strong SURF proposal is technical, clear, and well-structured. It should include:
- Background: Explain the theoretical basis and context for the research.
- Experimental or Analytical Methods: Detail how the project will be conducted.
- Project Significance: Demonstrate the contribution to the field and potential outcomes.
- Work Plan: Outline specific tasks and milestones over the ten weeks.
Returning SURF students are expected to submit proposals demonstrating greater depth and independence compared to first-time applicants.
Tip: Consult your mentor for guidance and review examples of previous SURF proposals to ensure clarity and technical rigor.
Recommendation Letters
Applicants must submit two recommendation letters:
- One from a faculty member, ideally someone familiar with the student’s academic or research abilities.
- One from a teaching assistant, research mentor, or other professional who can speak to the applicant’s strengths.
Mentors at Caltech provide a separate confidential evaluation of the student’s suitability for the project.
Additional Resources for International Students
International students must coordinate with their home institution regarding employment authorization:
- F-1 Students: May need Curricular Practical Training (CPT) or Optional Practical Training (OPT).
- J-1 Students: May require Academic Training authorization.
It is critical to begin this process early, as OPT processing can take three months or more.
Equal Opportunity Policy
Caltech is committed to inclusive education and provides an environment free of discrimination or harassment. The SURF program does not discriminate based on race, gender, religion, national origin, disability, or other protected characteristics. Questions regarding equity and Title IX compliance can be directed to: equity@caltech.edu.
