Saint Xavier University Biological Sciences


Biological Sciences Undergraduate Research

During the course of their studies, Biology major students may choose to participate in the Undergraduate Research Program in Biology (URPB). The URPB offers motivated students an opportunity to conduct original laboratory and/or field research in a variety of different areas of Biology under the guidance of a faculty mentor.
