Description
The Biology Program offers a major and a minor to students in the College of Arts and Sciences; several courses are offered for non-majors. In conjunction with various other programs, the Biology Program also supports an interdisciplinary major in biochemistry. Biology majors and minors pursue a diversified program that fulfills a breadth of interests and ultimately prepares them to pursue careers in many areas of the biological sciences, including education, research, and medicine. For those in related majors, the goal of the program is to focus particularly on the interfaces between biology and their major disciplines. Non-majors who take biology courses receive an exposure to biology to its fundamental concepts, latest discoveries, and modes of inquiry in ways that are relevant to their personal and professional lives and consistent with the objectives of the general education curriculum. Extraordinary developments in modern biology offer much to engage students at all levels.
Trinity offers students who study biology the advantages of close faculty-student relationships while providing access to the country’s primary resource collections, major research facilities, and outstanding internship opportunities at nationally recognized facilities.
