LIGO Summer Undergraduate Research Fellowships (SURF)


Summer Undergraduate Research Fellowships

June 21 - August 25, 2023
Caltech  ·  LIGO Hanford  ·  LIGO Livingston



All Fellows will need a computer; but because the size of the program, we cannot supply computers to students. If at all possible, plan to bring your own laptop.


If you will be working at Caltech: Please try, if at all possible, to arrive at Caltech a day or two before the program begins (June 14) and stay through the last day (August 19). On the last day, we have some student presentations, and a farewell BBQ/party.


Students in the Caltech LIGO Summer program receive a stipend. In 2021, the stipend was $6,620 for 10 weeks. The stipend is taxable. Travel expenses to and from your work site (Caltech, LHO or LLO) are covered by the program; as are expenses associated with a field trip to LHO or LLO during the summer.


Students in the Caltech LIGO Summer Program assigned to Caltech may live in Caltech campus housing during the program. Starting summer 2022, costs of Caltech campus housing will be covered by the program. You will be contacted by the Caltech Student-Faculty Programs (SFP) office, in early April, to make arrangements. Non-Caltech students should move into Caltech housing the day before the program begins unless other arrangements are made. More information is available at the Caltech Housing website. Housing at LIGO's Hanford and Livingston sites will also be provided for students based at these locations. Also, arrangements will be made for daily transportation to and from the sites.


Transportation to and from Caltech/Hanford/Livingston at the beginning and end of the program can probably be provided in full for all students.

Site-specific information

Students in the Caltech LIGO Summer Program reside either at Caltech or one of the LIGO sites in Washington or Louisiana. Specify your preference(s) on the application.
