Biography:

Dr. Jamie Strange has studied bee health and genetics for over 20 years. The Bumble Bee Health and Genetics lab primarily focuses research on the aspects of management, conservation, and biology of native North American bumble bees. Projects include understanding how environmental change (climate change, urbanization, agricultural management practices) impact the health of these important pollinators. We also study ways to improve captive rearing of bumble bee colonies that are used for crop pollination and for conservation of at risk species. Secondary projects focus on other native and managed bee species such as mason bees and leafcutting bees. Ongoing projects are funded by NSF, USDA, and USFWS. Dr. Strange teaches Pollinator Biology and Conservation (ENTMLGY 5150) during the spring semester of even years.
