Projects are often done in the research areas of the Department - from particle physics to astrophysics. A student wishing to do an interdisciplinary thesis may need an adviser in another department to provide the expertise in the related field, as well as a physics department adviser to oversee the physics aspects of the thesis. For more details, see Senior Matters . You may become involved with research as early as you want. The summer between the first and second years finds several students in Princeton working with research groups in the department.
More students become involved in later summers, and some students continue during the academic year.
It is even possible to work in a research group in the summer before your freshman year. Undergraduate researchers contribute in just about all the labs in the department. Summer research positions are arranged informally, with students meeting with individual faculty members. Start with any faculty member to get leads. You should prepare a brief summary of your background to bring with you.
