Research Interest

Dr. Percival's research interests lie in wetland wildlife, and have conducted long term collaborative projects on various aspects of alligator and migratory bird biology. He has teamed with geomaticists and aeronautical engineers to develop an unmanned aerial vehicle for assessment of wildlife populations and habitats. he has a special interest in natural resources administration, especially multidisciplinary, collaborative, and interagency research programs.
