Boulder Solar REU Program

The University of Colorado Boulder invites undergraduates to apply for a paid summer research experience for highly motivated students interested in solar and space physics. Students will come to Boulder, Colorado for 10 weeks to work on a research project with a mentor. The topic areas span the field of solar and space physics, from instrument hardware to data analysis to modeling of the Sun, the Sun-Earth system, the near-Earth environment, or the heliosphere.

Successful applicants will work with scientist mentors at one of these Boulder institutes:

The program begins with a week-long summer school in solar and space physics and continues with seminars and discussions while you work at one of the participating laboratories, providing peer collaboration opportunities. At the end of the summer, you will present your research findings. Please read through our FAQs for further details.

Frequently Asked Questions

What is the financial support of the program?

Yes, you will receive $600 per week, your housing will be fully covered, and you will receive a fixed travel stipend to get to and from Boulder.

Where will I be living if I am accepted into the program? Will I have roommates?

We provide and pay for a shared room at the Bear Creek apartments – a CU Boulder apartment complex. You will share an apartment with up to three others. Each person gets a private bedroom, but shares a bathroom with one other person and shares a kitchen and living space with the others. Some of the apartments are two-person, some are four. There are B-cycle bicycles, the University buses, and public buses that serve the Bear Creek area.

Do I have to live at Bear Creek with the other REU students?

We are happy to work with you to find the best solution for you for your summer. We want you to be successful and to remove as many obstacles as we can. If you have a family and need larger accommodations, or live a commutable distance away, we can give you the value of the Bear Creek apartment towards your living expenses.

What happens if I already have a commitment during the program?

If you have a tour of a college campus, or other educational or professional engagement, then you can work with your advisor to take some time off for that. However, we don’t encourage vacation planning or other optional time off during the program. Ten weeks is a very short amount of time to accomplish a research project so we expect you to be present from 9am-5pm every day unless circumstances are exceptional.

I have a full-time job nearby. Can I do both?

This program will be a full-time job. You will be expected to be at your lab from approximately 9am – 5pm Monday to Friday (times are flexible under agreement with your advisor). We do our best to give you the financial support to make participating possible. However, part-time work after hours or on the weekend is possible if necessary.

I love astronomy and cosmology. Can I study that in your program?

This program has a focus on research inside our solar system – the Sun and the planets. Occasionally we will have extra-solar projects but, more than likely, they will still have a planetary science focus. Studying galaxy formation or stellar evolution is not likely something you’ll be able to do here. Instead, you’ll be focusing on solar eruptions, space weather effects, the dynamics of the ionosphere, the Earth’s magnetosphere, sunspot evolution, what drives the solar dynamo, and many many other super cool projects!

I am transgender/gender non-conforming. What would my housing situation look like?

There is flexibility in the housing arrangements, and we will find a situation that you are comfortable with.

If I am accepted, how do I make travel arrangements to get to Boulder? When should I travel?

After you are accepted, we will send you a travel stipend that you can use to make travel arrangements that suit your needs. Some students drive to Boulder, others use it for airfare. We can help make travel arrangements if you are uncomfortable making them yourself.

My school doesn’t finish until after the program begins. Can I still participate?

Yes, students on the quarter system typically are not out by the end of May. We will accommodate your schedule.

I don’t know anything about space physics. Should I apply?

If you don’t know about space physics but think it sounds really cool, then we suggest you do a little investigating into the partners on this program and see if you think their work sounds interesting. You don’t have to have any experience or detailed knowledge about space science to participate, but you should know that its a topic that interests you. Your personal statement is the place to tell us about why it interests you, or why you think it could interest you. Also, check out this youtube video where alumni discuss how they felt before starting the program.

I don’t know which broad science areas to pick

That’s OK! The great thing is, this is a good opportunity to do a little research into what these broad science areas are and if any of them sound particularly interesting to you. You don’t have to have studied them before, or know much about them. We ask this question to help match you with mentors and projects. If you don’t have any preference, or would be happy to study “all the things”, then you can always select “no preference”.

What criteria are applications reviewed on?

Each application is reviewed on a range of criteria that include personal motivation and determination, your interest in research and space science, and how much this program might impact your future career. We are looking to recruit hard-working, motivated students who will be strongly impacted by this program. Prior experience is not required. One of the goals of the program is to provide an opportunity to gain experience. 

The criteria used to review applications include (but are not limited to): 

  • Impact the program will have on the applicant in their career and education 
  • What the applicant will contribute to the cohort 
  • Level of applicant’s interest in the research area

Additionally, grit and resilience are shown to be good indicators of successful researchers. Having the perseverance to stick with a problem, even in the face of adversity or challenges, is a skill that many researchers possess. Make sure to explain how you have demonstrated grit and resilience in the past. 

My letters of recommendation haven’t been submitted by the application deadline. Will I be disqualified?

Letters of reference help the review committee get an external view of your educational experience. We will evaluate your application based on as many letters of reference that we receive. Once you apply, we will send a separate email to each referee that you listed with their own deadline for submitting a letter of reference. Please contact your referees to check on their timeliness. Contact us if unique circumstances prevent a letter of reference from being submitted on time.

What does the selection process and timeline for offers look like?

The application deadline is at the end of January. A committee of reviewers will go through all applications and create a shortlist of the top 100-or-so applications. Each mentor is then sent between 5 and 10 of the shortlisted applications that best suit their project needs. The mentors identify their top applicants from their 5-10 shortlisted candidates and offer letters are sent out. If applicants are selected by more than one mentor, the applicant is given the choice of project. If the mentor’s first pick of applicant rejects the offer, the next choice is then offered the project and so on until all projects are filled. The first round of offers will be made around March 1st.

Do I get to choose the institute, mentor or project?

We use the information on your application to match you with a project/mentor that you might be interested in. The mentors will select their preferred applicants from a shortlist of 5-10 students. If you are selected by more than one mentor then you may be asked to choose between them. If you are selected by one mentor then that would be the project/mentor/institution you’d be working on/with/at for the summer. So if you have strong preferences about your topic or institute, it is best to make that really clear in your application.

How many students do you accept?

We recruit between 18 and 25 students each year, depending on funding.

We ask three essay style questions, each between 250-1500 characters. The questions are broken out as they are to help us identify who would benefit most from the program. Remember that this is your chance to make your case for the program. It is important to set yourself aside from your peers in responding to these questions. Specific responses are more effective than generalizations or wistful reminiscing. Tell us how this program might change your life.

  • Personal Statement. Please tell us why you are applying to this program in particular.
    • This is a general overview of you, your interest in the Boulder Solar REU program specifically, and why you decided to apply for the program. What are your interests in solar and/or space physics and in Boulder. This is a good chance to help us understand who you are and what you hope to get out of the summer experience.
  • Please tell us how this opportunity will help you in you achieve your educational and/or career goals.
    • REU programs are well known to boost applications for graduate school programs, and giving students the chance to test out a research career. Please explain your specific circumstances, and how this program will help you achieve your educational and career goals, or help you to identify what your goals might be.
  • Tell us about a time when you have shown grit, determination, and motivation to overcome adversity and succeed in your goals
    • Research can be very challenging and sometimes even demoralizing. One of the most effective skills in successful researchers is that of grit and resilience. Research frequently means exploring the unknown, trying many routes to an answer, and failing frequently but persisting anyway. Tell us about your resilience and a time when you have succeeded against the odds, or at least tried to.
