Dr. McGrann studies creation because it reveals God’s character (Romans 1:20), God’s providence and love (Mathew 6:26-27), and God’s promise to restore (2 Peter 3:10-13). He also draws inspiration from his wife, two sons, and daughter…and his students. He believes that he is walking in obedience and is thrilled to be part of what God is doing here at Jessup. He enjoys working with students and getting them out of the classroom and learning to do science in the field

Dr. McGrann's main research interests lie in questions of montane avian community ecology, species-environment relationships with elevation, wildlife-habitat associations, and habitat classification. He has participated in a wide range of conservation and applied ecological research.
