Jason S. Kilgore, Ph.D.

Associate Professor of Biology; Environmental Science Major Coordinator

Degrees: Ph.D. Plant Biology, and Ecology, Evolutionary Biology, and Behavior Program; M.S. Botany and Plant Pathology, and Ecology and Evolutionary Biology Program; B.S. Conservation and Environmental Management; and B.S. Environmental Sciences, Michigan State University

Jason Kilgore is an associate professor in the Department of Biology and serves as the coordinator for the Environmental Science Major. As a broadly trained plant ecologist and former wetland consultant, he is interested in the regulation of species distributions from local patches of woods to the landscape scale. He and his students use field and greenhouse studies, integrated with GIS, to understand the impacts of invasive species, environmental contaminants, and climate change on growth, survival, community succession, and migration of plants.

Dr. Kilgore’s main research systems include the mountain islands of southern Arizona, Great Lakes sand dunes, and eastern deciduous forests of North America. He particularly values long-term ecological studies and participates in the College’s Long-term Ecological Monitoring (LEM) program at the Abernathy Field Station and the Permanent Forest Plot Project (PFPP), which is part of the Ecological Research as Education Network (EREN). Within EREN, he is co-leader for the Emerald Ash Borer Impacts Study (EAB) and Complementary Vegetation Survey (cVeg) and contributor to collaborative projects related to garlic mustard (GM/P), acorn production (OakMAST), and impacts of windows on bird mortality (BirdWin). Recent research also includes developing protocols to identify old-growth forests in the local ecoregion.

He is also involved in research related to spinal cord stimulation with Dr. David Provenzano, impacts of collaborative research on student learning (EREN), use of digitized natural history collections to learn ecological concepts (QUBES Faculty Mentoring Network), and remediation of soil and water contaminated with heavy metals (Luce Initiative on Asian Studies and the Environment (LIASE) Grant, Henry Luce Foundation), which is work done in collaboration with W&J students, Dr. Jennifer Bayline (Chemistry Department), and faculty at Guangdong University of Education in Guangzhou, China.

Dr. Kilgore is also founder and curator to the W&J Campus Arboretum and manages the W&J Greenhouse and Herbarium. Many students from across campus contribute to the care, management, and monitoring of plants in these projects.

Dr. Kilgore’s primary teaching responsibilities are Evolution and Biological Diversity, Field Biology, Applied Statistics for the Life Sciences, Plant Diversity, Environmental Plant Physiology, and Forest Ecology. He also teaches an introductory course in environmental studies related to water resources as well as non-major courses in economic botany and First-Year Seminars focusing on discovering one’s sense of place and thriving as a first-year student. Dr. Kilgore teaches on-campus Intersession courses in dendrochronology and travel courses focusing on the natural and human history of the Sonoran Desert.

Dr. Kilgore currently serves the College on the Graduate Program Committee and as chair of a workgroup for Middle States Accreditation. He also serves as the faculty mentor to the Varsity Baseball Team and advisor to the Adventure Club.

Community service is very important to Dr. Kilgore. Among other activities, he serves on the City of Washington Planning Commission, gives talks and field trips to community organizations, develops and leads outreach activities to local schools, is a regular volunteer with Produce to People (Washington County Foodbank), and is a Merit Badge Counselor and Committee Chair for Boy Scout Troop 1315.
