Intern with Breakthrough Listen

“As close to a perfect summer internship as you can get.”
“Had a profound impact on my academic trajectory.”
“The best overall professional experience I've had to date. The quality of the training and mentorship was great. It was the best-organized internship I've had too, and the best social experience I've had in an internship.”
“I would not be where I am, or who I am, today without my experiences working with the Breakthrough Listen team.”

Program Overview

Current undergraduates are invited to apply for research internship positions with the Breakthrough Listen project. Breakthrough Listen is the world's most comprehensive, intensive, and sensitive search for extraterrestrial intelligence. We seek a scientific answer to one of humanity’s oldest questions: Are we alone in the Universe?

Our scientists and engineers are pioneers in the development of software, instrumentation, and science strategy for the search for intelligent life on other worlds. We have access to substantial amounts of time on the planet’s largest telescopes, and connections and collaborations with some of the leading players in the tech industry. We’re also psyched that we get to wake up each day and hunt for aliens.

Summer interns work at the cutting edge of the search. If you are motivated, work well as a member of a team, and can take initiative and responsibility for your own work, you’ll fit in well in our group. Interns have gone on to graduate school at UC Berkeley, Caltech, Columbia, Cambridge, Oxford, and many other prestigious institutions, in addition to careers at Facebook, Google, and other leading companies.

Example Projects

The list of available projects changes from year to year. Students are paired with mentors based on their interests and skillset. If there are particular areas of our research portfolio that interest you (you may want to check out some recent papers or press releases mentioning Breakthrough Listen), we'd like to hear about them in your application. Some example projects from previous years include:

The Weirdest Stars on the Sky: A Multiband Follow-up - Lana Tilke (Connecticut College)
Lana worked with Dr. Ann Marie Cody to search for indications of engineered megastructures around stars. Applying machine learning techniques to data from NASA's Transiting Exoplanet Survey Satellite, Lana explored a huge set of archival lightcurves to find anomalies which could be technosignature candidates or signs of interesting astrophysics. Lana received a 2022 SETI Forward award in recognition of her research, and is now studying for a PhD in Astrophysics at Arizona State University.

A Search for ETI around Proxima Centauri - Shane Smith (Hillsdale College)
Shane worked with Dr. Danny Price and Dr. Sofia Sheikh (also one of our former summer interns!) to search for radio technosignatures in data from the Parkes radio telescope. Although he didn't find ET, he did get a first-author article in the prestigious Nature Astronomy journal and coverage in the New York Times, Scientific American, National Geographic, and elsewhere. Shane is now an engineer at the Aerospace Corporation.

Radio Technosignature Searches of Nearby Galaxies - Carmen Choza (University of Chicago)
Carmen worked with Dr. Steve Croft to search for radio technosignatures in a sample of 100 nearby galaxies observed with the Green Bank Telescope. This is one of the major components of the Breakthrough Listen program as announced at the Royal Society in London in 2015. Carmen's first-author paper presenting the analysis of this huge observational dataset was published in the Astronomical Journal, accompanied by a press release. Carmen is now studying for a SETI-related PhD at the University of Oxford.

Other interns have written high performance computing pipelines for the MeerKAT telescope, developed a citizen science platform for technosignature searches in collaboration with Zooniverse at Oxford University, searched for fast radio bursts, looked for laser signals in spectra from the Automated Planet Finder telescope, simulated populations of Doppler drifting signals from the known properties of exoplanetary systems, and much more!

Application Details

For 2025, we are offering internships in the USA, Ireland, UK, and Italy. We are unable to sponsor visas so please carefully read the eligibility criteria below for the country for which you are applying. Women and nonbinary students, underrepresented minorities, transfer students, and others traditionally underrepresented in science are strongly encouraged to apply.

The majority of our projects make heavy use of modern programming languages and tools. While we don’t expect applicants to be experts in all of these areas, familiarity and experience with one or more of Python / Jupyter, version control (e.g. git / github), database software (e.g. MySQL), visualization tools (e.g. Bokeh, D3, etc.), GPU programming, interface design, machine learning, cloud computing, Unix / Linux scripting, and / or public outreach will make for a strong application. Prior astronomy research experience is not a prerequisite, although if you have knowledge or experience of observational astronomy (optical, radio, or other wavebands), signal processing, and / or data reduction we would like to hear about that in your application. We'll also train you up on GNU Radio and you'll have the opportunity to operate some of the planet's most powerful radio telescopes - again, no prior experience is required, but we would like to hear about it if you have any.

If you are eligible for more than one of the international programs (please carefully note citizenship requirements) feel free to complete more than one of the relevant application forms. If you're only eligible for one site, please make sure you fill out the correct form!

If you've thoroughly reviewed the instructions here and still have questions, feel free to email us at reu@berkeley.edu.

Opportunities in the USA (applications now closed for 2025)

Our US program takes place in person at UC Berkeley. Current sophomore, junior, and senior undergraduates (at the time of application) are eligible. The program is open to US citizens, legal permanent residents ("green card" holders), and non-citizens who are already enrolled at degree-granting institutions in the United States (e.g. F1 visa holders, DACA recipients). We cannot sponsor visas for other international students - if you don't already fall into one of the above categories, please don't apply.

Here’s what you’ll need to apply:

• A recent transcript (unofficial is fine)
• A CV
• A letter of recommendation from a faculty member, researcher, or other academic mentor. Please note that only one letter is requested - subsequent letters will be discarded and do not improve your chances of selection.
• A cover letter, which should include details of
  • What specifically interests you about SETI, our research, and the program
  • Your programming experience (including projects worked on)
  • Any prior research experience
  • Any other relevant information

By applying, you commit to being available for 40 hours of work per week (June 9 – August 15, 2025). You’ll be expected to work closely with other interns, to consult with our researchers as necessary, and to attend weekly meetings and lectures. The week of June 9 - 13 will consist of an intensive week of preparatory lectures, and the remainder of the summer will consist of independent research. You’ll be expected to keep notes on your progress, to check your code in frequently to github, and to keep in touch with us on our Slack account.

A stipend of $11,478 is provided, which is intended to cover all of your expenses during the program including meals and accommodation. Additionally, travel costs to and from the program site will be reimbursed - instructions regarding booking and reimbursement will be provided to accepted students. Transportation, food, and accommodation will also be provided for field trips to Lick Observatory and to the Allen Telescope Array. Funding is also available to support interns who successfully complete the program to present their work at meetings such as the American Astronomical Society meeting.

To apply (US ONLY):

• STEP ONE: make a single PDF format file containing your cover letter, recent transcript, and CV. The name of this file should be Lastname_Firstname.pdf (e.g. Sagan_Carl.pdf).
