Advice on undergraduate research I am a junior in college who is very interested in doing some sort of REU/research internship in theoretical computer science this summer, as I would like to get research experience before potentially applying to grad school. However, I have not had much luck in finding many research opportunities. The most theoretical focused one I stumbled upon was at the Toyota Technological Institute at Chicago, but I want to apply to more than just one program, of course. If anyone has any advice or knows of any good research opportunities for an undergrad in theoretical computer science I would love to know, as I am beginning to have difficulty finding other options.
Here is a tweet thread by Prof. Vijay about research for undergraduate students.
Also, you can apply for a summer research internship in Europe.
