Join Our Team of Student Researchers


We encourage interested students to take relevant linguistics courses before considering lab work, especially Spanish 298 ("Introduction to Spanish Linguistics"), which is offered every Fall and Winter term and often in Term III. This background knowledge will help you better understand and contribute to our research projects. We frequently recruit research assistants directly from these courses, or through the Research Opportunity Program (UROP).

Any specific questions can be addressed to principal investigators Nicholas Henriksen and Lorenzo García-Amaya at nhenriks@umich.edu and lgarciaa@umich.edu. The best time to express interest is in the summer or the weeks leading up to the start of the semester.
