Biology serves as a large umbrella for many kinds of scientists and professionals. Biologists conduct basic and applied experimental and clinical work in both the public and private sectors?in the field, in zoos and wildlife refuges, in laboratories, and in medical settings. Just a few of the areas in which they work are wildlife and field ecology, conservation and environmental restoration, pharmaceuticals, biotechnology, and forensics. Although students with a BA may find employment as laboratory technicians, wildlife monitors, and other entry-level positions, those who hope to pursue a research career should plan to go on to graduate school.?
