The information in biology textbooks was once cutting-edge research… and someone had to do the behind-the-scenes work to discover it. You will have the opportunity to seek professional internships and off-campus research programs as you advance in your studies. Graduate from Trinity prepared to go into any number of fields, including environmental conservation, research, or even bioethics.
