Science Undergraduate Laboratory Internship (SULI) Program

Program Overview

Summer 2024 Term SULI Applications are due January 9, 2024 5pm ET. You can apply here.

SLAC National Accelerator Laboratory is a world-renowned laboratory with research opportunities in physics, chemistry, materials and environmental sciences, astrophysics, scientific computing, and many engineering fields. SLAC’s summer internship program offers exciting opportunities for undergraduate students majoring in science or engineering to conduct research.

The SULI Program is sponsored by the Department of Energy (DOE) Office of Science's Office of Workplace Development for Teachers and Scientists (WDTS).

The 2024 summer program at SLAC will be in-person and runs for 8 or 9 weeks. Students selected for internships receive:

  • Stipend ($650 per week)

During the internship, each student works with a scientist or engineer on a project related to the Laboratory’s research program. At the conclusion of the internship, the student writes a research paper and makes a brief presentation on his or her project. Students also participate in a series of scientific lectures, professional development workshops and tours. Student projects range from solar-cell technology to astrophysics, from cancer drug research to particle physics and accelerator design, and from biocompatibility of medical devices to ultrafast (femtosecond) phenomena.
