Under the leadership of Dr. Kenneth E. Peacock (2004-14), Appalachian became a destination of choice for high-achieving, intellectually curious students wanting to be engaged in the community. In addition to small classes and challenging academics, Appalachian became known for its undergraduate research, internationalized curriculum, service-learning and sustainability, both in academic programs and campus practices. The university grew significantly in the areas of healthcare and the nexus of energy, the environment and economics.
