Science Undergraduate Laboratory Internships: Launching STEM Careers
The Science Undergraduate Laboratory Internship (SULI) program represents a significant opportunity for undergraduate students pursuing careers in science, technology, engineering, and mathematics (STEM) fields. By providing research experiences at Department of Energy (DOE) laboratories, SULI aims to cultivate the next generation of scientific leaders. This article delves into the program's structure, benefits, eligibility requirements, and application process.
Overview of the SULI Program
The SULI program is sponsored and managed by the DOE Office of Science’s Office of Workforce Development for Teachers and Scientists (WDTS) in collaboration with DOE laboratories/facilities. Each year, students from across the nation participate in SULI at one of the 17 participating DOE laboratories/facilities, gaining invaluable experience and contributing to the Department of Energy’s (DOE’s) diverse missions. The program is a paid internship opportunity, offering students not only a chance to learn but also financial support.
Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) are among the participating institutions. ORNL, a national leader in science and engineering for 80 years, offers opportunities across nearly every scientific discipline. PNNL provides a comprehensive internship experience, pairing students with leading science experts in specific research areas.
Internship Structure and Duration
SULI offers three separate internship terms annually:
- Summer Term: A 10-week internship running from May through August.
- Fall Term: A 16-week internship from August through December.
- Spring Term: A 16-week internship from January through May.
The length of the appointment for the summer term is 10 weeks (June through August). The length of appointment for the spring and fall terms is 16 weeks (January through May for spring, September through December for fall).

Benefits of Participating in SULI
Participating in the SULI program offers numerous benefits, shaping students into well-rounded professionals ready for future STEM careers. Some of these benefits include:
- Research Experience: Interns work on projects supporting DOE missions under the guidance of scientists or engineers, gaining hands-on experience in their field of study.
- Networking Opportunities: SULI provides opportunities to connect with leading scientists and engineers, expanding professional networks and opening doors to future collaborations.
- Skill Development: Interns develop technical skills, enhance their problem-solving abilities, and learn about the operations of national laboratories.
- Financial Support: The program offers salary, travel, and potentially housing reimbursements for eligible students, reducing the financial burden of participating in an internship. All students at PPPL receive a $650/week stipend; an additional housing grant is dependent on funding availability. Most travel-related costs are covered by the program. Housing costs are also covered by the program.
- Exposure to Diverse Fields: SULI exposes students to a wide range of research areas, helping them discover potential career paths they may not have considered.
- Enhanced Internship Experience: At PNNL, interns are invited to participate in the Gold Experience, which includes comprehensive onboarding, tours of facilities, seminars, workshops, and professional development opportunities.
Eligibility Requirements
To be eligible for the SULI program, applicants must meet specific criteria pertaining to enrollment status, academic standing, and citizenship:
Enrollment Status:
- Currently-enrolled students: The applicant must be currently enrolled as a full-time undergraduate student at an accredited institution (including accredited community colleges and 2-year colleges) and also have completed at least one semester as a matriculated undergraduate student at the time of applying. Students enrolled at colleges and universities on the quarter system must have completed at least one academic quarter. Grades for the completed semester must be shown on the submitted transcript(s).
- Applicants, including freshmen, must have completed at least 6 credit hours of postsecondary courses in science, mathematics, engineering, or technology disciplines, and must have completed at least 12 credit hours towards a degree by the time they apply. Credit hours and grades must be reflected on the submitted transcript(s).
- Advanced Placement credits or other undergraduate credits obtained prior to undergraduate enrollment cannot be applied to meet the minimum one-term completion requirement.
- Full-time enrollment status is determined by the number of hours or courses the school requires for full-time attendance (as defined by the Internal Revenue Service).
- Recent graduates: Applicants who will have completed their undergraduate degree prior to starting their internship may apply as a "Recent Graduate." This includes students who have graduated with an associate's degree or bachelor's degree, those who have completed a combined BS/MS program, and those who have completed an undergraduate degree and are now enrolled in a graduate studies program. The time period between receipt of an undergraduate degree and starting the SULI term must be two years or less.
GPA: Must have a cumulative minimum Grade Point Average (GPA) of 3.0 on a 4.0 scale for all completed courses taken as a matriculated student at the applicant's current (or recently-graduated) institution and at any institutions attended as a matriculated postsecondary student during the 5 years preceding the start of the most recent enrollment.
Citizenship: Citizenship or Lawful Permanent Resident (LPR) status will be requested at the time an internship offer is accepted. citizen) Abroad, or Certification of Birth.
