Computer Science REU: Admissions & Acceptance Rates

AI Thread Summary
The discussion centers on the pursuit of advanced studies in computer science, particularly focusing on the importance of research experience for undergraduate admissions into PhD programs. The participant, a rising sophomore at a top U.S. school, has taken introductory programming courses and is interested in furthering their knowledge through additional computer science and math classes. They express concern about the competitiveness of Research Experiences for Undergraduates (REUs) in computer science, noting a lack of accessible information compared to math REUs. The participant shares their experience with a highly competitive REU application process, emphasizing that acceptance rates can be quite low and that applying widely is essential. They also mention the possibility of working with a professor at their institution if they cannot secure an REU. Overall, the conversation highlights the challenges of obtaining research experience in computer science and the need for strategic application approaches.

Hello everyone. I've gotten interested in the field of computer science lately, and I'm thinking of pursuing advanced study in that field. I am currently a rising sophomore at a top 10 school in the U.S. and will likely major in computer science (if not, math). I would like to know a little more about admissions with computer science research experience for undergraduates. I haven't found that much information online as compared to, say, math REUs.

So far, the only computer science classes I've taken are the standard two intro classes - programming I and programming II in Java. However, I've been exposed to a lot of graduate-level projects in computer science that intrigued me, especially with AI, 3-D rendering, algorithms, and others. I plan to take, at minimum, 3 more computer science classes in the next school year, as well as related math classes.

I've looked at some REU's in computer science, but most don't give me a lot of information about admission. How valuable are they for an aspiring PhD student? Is the acceptance ratio greater than or less than 10 percent? What are the most competitive and least competitive REU's to get in? (I'm not saying that there are bad REU's - I just want to see if I can get in one after my sophomore year and I'm aware that I'll be aiming low to start.) I'm hoping to eventually get accepted to a PhD program in computer science ranked in the 20-30 range.

The REU I am in right now, an Earth science one, had 485 applicants for 10 or so spots (there are 30 ish interns but 20 came from the original school and were not included in the same applicant field). Suffice to say that REU's are super competitive, and they don't necessarily accept the best students. I applied to 10 and only got into one, which happened to be the most competitive one by chance. Its basically a crapshoot. Don't aim low, aim wide. Apply to all that interest you.
 
That's disappointing, and I will aim wide. But there have to be some programs that are not as competitive, i.e. they accept 10% of their applicants rather than 3%. I'll try and ask around more in my school. If I can't get an REU I suppose working with a professor at my school is the alternative.
 
Does anyone else have thoughts?
 
Tell them you're black. And poor. And don't tell them you go to a good school, say you're from a community college.

Otherwise, if you're not the best student in your department, you will be hard up.
 
Well, I do fall in the category of minorities, but of course that's no guarantee. Anyway I'll just be doing my applications, then. It's weird to see a lot of math and physics REU topics here, but not many computer science REU topics given that computer science relates a lot to math and physics.
 
TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
