For Fermilab Staff

First of all, thank you for considering supervising a talented student intern from the Fermilab SIST program!

These students are free to your group (except for overtime). So, in this climate of tight budgets here is a way to get free help for your projects.

Getting an Intern

To get an intern to help with your project(s),

please send an email to us

(You will have to adjust the "TO" line in this message) describing the job you have in mind. The initial contact can be brief, for example, "I want an intern, please. Sincerely, etc.." We will contact you for more information later.


Please take a moment to review our Guidelines and Expectations for Interns and Supervisors document.

Final Talks

SIST interns will be documenting their work in a journal style write up. In addition to the paper the interns will be making a 15 minute presentation in early August, 2015. SIST commitee members are available all summer to act as mentors and help the interns prepare the paper and talks, as well as answer any questions.

Details about program dates, housing, transportation, etc. is available in our intern Fact Sheet.
