External Internship and Research Opportunities for Undergraduates

Skip down to a section:

Pathways to Science is a portal website supporting pathways to the STEM fields: science, technology, engineering, and mathematics. Particular emphasis is placed on connecting traditionally underrepresented groups with STEM programs and resources, including funding and mentoring opportunities. Use this website to search for programs in STEM, including undergraduate summer research opportunities. is a newer portal to help undergraduate students search for Federally-sponsored opportunities in STEM fields.  You can filter by type of opportunity, including Fellowships, Scholarships, Courses or Summer Schools, Internships (research and non-research), and more.  (Students will usually not want to sort through the "University/Institution-based Awards for Undergraduate Programs" listings, so we recommend that you do use the filters to help narrow your search.)  Since these programs are federally sponsored, expect that they will mostly require U.S. Citizenship.


Internships are a great way to gain work-related experience prior to graduation, possibly earn some money, and in some cases, they have led to offers of permanent jobs for our students after they graduate.

Earning Credit for an Internship

Students who already have an internship lined up may earn credit for the experience; Internships with significant mathematical (MATH) or statistical (DATA) content as determined by one of our designated internship coordinators may be considered for credit under the appropriate prefix. Math Department internship guidelines, policies, and procedures are available in our knowledge base here. (For other internships, credit may be earned under LASC; details are available here.)

Finding an Internship

UA Career Services is the most up-to-date source for information on internships available to students through the Handshake platform. Any student searching for a job or internship should create a profile in Handshake. Career Services can also help critique your resume, hone your interview skills, and more - see the Life Lab details on the website to get started. 

The American Mathematical Society (AMS), Society for Industrial and Applied Mathematics (SIAM), and American Statistical Association (ASA) all maintain listings of internship opportunities on their websites, as does the Hispanic Association of Colleges and Universities (HACU) of which UArizona is a member:

Below is a selection of companies that offer internships for undergraduate students majoring in mathematics and/or statistics. 

Aerospace and Defense

Actuarial and/or Risk Management

Summer programs away from the UA

Many university departments and government labs run summer research programs for undergraduate students, often under the acronym REU (Research Experience for Undergraduates). Since availability changes each year, it is best to learn about current offerings through the following listings:

Application deadlines are frequently flexible; therefore, if you are interested in applying for a program for which the deadline has passed, contact the program anyway. It is possible that they still have openings and would consider your application.

Dr. Velez compiles a brief list of REU programs each year that may have fewer prerequisites than most, or that may be open to specific populations (future teachers, international students, etc.). Click the link to see the most recent list. It is usually published around January. 

Select summer programs

To get a flavor of what might be available, information on select programs appears below.

Amgen Scholars Program

(Various locations) The Amgen Scholars U.S. Program provides hundreds of selected undergraduate students with the opportunity to engage in a hands-on research experience at some of the nation’s leading educational institutions. Currently, 10 universities in the U.S. host the summer research program. Research areas include Statistics, and many of the life sciences (applicants will be interested in pursuing a Ph.D. or M.D.-Ph.D.). Note that the European program is currently only open to students from European univerisities.

EDGE Program

(Bryn Mawr, PA or Atlanta, GA) Enhancing Diversity in Graduate Education is a program funded by the National Security Agency and is designed to strengthen the ability of women and minority students to successfully complete graduate programs in the mathematical sciences. Applicants to the program should be women who are

  1. graduating seniors who have applied to graduate programs in the mathematical sciences,
  2. recent recipients of undergraduate degrees who are now entering graduate programs, or
  3. first-year graduate students.


(Piscataway, NJ and Prague, Czech Republic) DIMACS, with National Science Foundation sponsorship, has offered an REU program since 1992. There are four associated REU programs:

IPAM Research in Industrial Projects for Students (RIPS)

(Los Angeles, CA, or Hong Kong) RIPS is a program for students who are enrolled in or have just completed an undergraduate (bachelors) degree. Students with a strong background in mathematics and an interest in seeing how mathematics is used in the real world are encouraged to apply.  RIPS is not exactly an REU - the projects come from industry rather than academia, so it is essentially a cross between an REU and an internship. RIPS students do not have regular interaction with the faculty or students of the math department, except for the academic mentors.  There are no classes during RIPS; the focus is entirely on the research projects, and ultimately presenting the results.  Most of the projects have a significant computational component, so that proficiency (or at least some experience) in computer science, data analysis or numerical computation is valuable, but not necessary for everyone.
