Are you interested in research but unsure about the various roles in a psychology research lab? Here at Michigan State, we have a variety of psychology labs – from ones that use lab coats and microscopes to ones that focus on surveys, community listening, and very large datasets. What’s all in common are the various roles that make up the lab! Each role is important – take a look to see where you may fit in!
Principal Investigator (PI)
The PI is the leader of the lab and an MSU Psychology faculty member. Most likely they are the namesake of the lab, so the lab’s interests are related to the PI’s area of focus. Depending on the size of the lab, the PI may directly collaborate with and mentor graduate students, lab managers, and undergraduate researchers. The PI is responsible for applying for grants to ensure funding, as well as for ensuring ethical and responsible research practices.
Post-Doctoral Students (Postdocs)
Postdocs have already earned their PhDs from another school and are well experienced with research. They typically work independently for 2-5 years in a lab depending on funding availability so they can continue their research and get more experience. They report directly to the PI.
Graduate Students
At MSU Psychology, graduate students apply to join a specific research area that aligns with their interests. If accepted, they join the department for 5-6 years while they obtain their master's degree and then their doctoral degree. Each research area differs slightly, but they are often assigned teaching roles (TAs) or research fellowships. In the lab, they work directly with the PI on research questions. They may also have a role in mentoring undergraduate students. Toward the end of their PhD, they write and defend a thesis that then contributes to the scientific community.
Lab Managers
In many labs, especially large ones, there is a lab manager that ensures things run smoothly. They oversee the daily operations, order supplies, coordinate projects, and may assist in training research assistants and answering questions. The needs and the size of the lab dictate how much time is spent on research activities or on organizational or management activities.
Research Assistants (RA)
A research assistant is perfect for undergraduate students who are looking to gain research experience in a lab setting. There are many volunteer positions, as well as paid opportunities. Those who stay with the lab long-term can take on more responsibilities and become more involved. You may work directly with the PI or with a postdoc or graduate student. This is a great chance to obtain a strong letter of recommendation and gain experience in doing quality research. In some cases, students may even present their research or be involved with publishing a research paper.
