The Harvard Stem Cell Institute (HSCI) Internship Program (HIP) provides undergraduate students with a focused and challenging summer research experience in a cutting-edge stem cell science laboratory. Interns are exposed to different professional options within the scientific arena through a stem cell seminar series, a career pathways presentation, and a weekly stem cell companion course. Students present their summer research findings, both orally and in poster format, at the HIP Symposium—a requirement of all program participants.
