Ive been with my current lab for 1.5 years. I was planning on doing some research in my last summer at my school from May to August (I graduate in aug). Are 4 months long enough to expose myself to a different lab and to broaden my research experience? If I do stick to my current lab, I will be doing the same thing in the summer. My PI doesn't really offer great opportunities to be independent and my lab is limited to what we can do. However, I do know another PI that will be able to let me work on a whole new independent project.
