Volunteering in a research laboratory is an excellent way to gain additional experience in the field. You can volunteer in labs at any point in your undergraduate career. You are encouraged to get involved as early as possible. Many labs do not take students who ask to start volunteering in their senior years.
If you are interested in this possibility, begin by reading about the faculty and the associated labs in the Speech, Hearing and Language Sciences department. After determining which labs are of most interest to you, reach out to the faculty member to ask whether they are currently accepting volunteers.
The requirements for volunteering in a lab vary widely. For some labs, there are no specific requirements other than an interest in learning more about research. For other labs specific skills, course work, or experiences may be required (e.g., proficiency in Spanish, having taken S311).
