Do undergrads get research opportunities?
Undergraduates definitely get research opportunities. There are many (world-leading) laboratories on campus where undergraduates engage in research as early as their freshman year. And there are plenty of opportunities to go around. Im not a science concentrator, but I know that all of my friends who have been interested in working in labs here have gotten the chance to do so. In addition, Harvard supports a wide range of research outside of the campus gates. Undergraduates have access to a huge array of undergraduate research grants for term-time or summer work. I just received a grant so that I can go to China this summer to do research for my thesis.
