Dr. Timothy Keitt grew up in North Florida, where he developed a passion for observing nature while tagging along on field trips with his father, an avid, life-long birder. He studied zoology as an undergraduate at the University of Florida and later received his PhD in ecology and evolutionary biology from the University of New Mexico. In graduate studies, he discovered a parallel passion for computer science, and has made his career combining these interests. The major question of his research is how environmental variation in time and space, manifest at multiple scales, influences the dynamics of populations, communities and ecosystems. To these ends, he employs mathematical and computer modeling, statics and field studies. Recent work includes field studies of bird populations responding to changing climate and landscape fragmentation, and the application of machine learning to environmental monitoring with sensor networks. He is a professor and the Associate Chair for Undergraduate Education in the Department of Integrative Biology at the University of Texas at Austin, where he teaches ecological theory and field ornithology.
