The Program to Inspire and Mentor Undergraduates in Environmental Health Science Research (PrIMER) is a research program for full-time, undergraduate students attending colleges and universities in the New York City area. Trainees can enter the two-year program in June before their junior year. They will be paired with a Columbia University faculty member who will serve as a mentor throughout the program. Trainees will conduct research in environmental health science, attend weekly professional development workshops, interact closely with Columbia University faculty, and receive compensation for their research throughout the program.
