Science Center 125


Dr. Lehman is a broadly trained plant biologist with interests in host-plant interactions, plant toxicity, tropical and temperate agriculture, and the evolution of cultivated and natural plants. He teaches courses in genetics, plant diversity, plant physiology, dendrology, and tropical ecology/agriculture. Dr. Lehman’s research addresses: 1) the interactions between plants and their pathogens, 2) the toxicity of leaf extracts of Acer species to horses, and 3) the evolution of dioecy. Dr. Lehman also directs service-learning projects (e.g., semi-annual plant sale) and leads courses to Costa Rica and Malawi.

Dr. Lehman’s hobbies/passions include sustainable agriculture, plant propagation, old tractors, microscopy, wood-burning stoves, international foods, and assorted genres of music. His dream is to develop his own sustainable mini-farm. He is often busy fixing the myriad of broken things on his farm. This has led his son Caleb to exclaim, “If it isn’t broken, dad doesn’t want it”. In addition to having a sarcastic son, Dr. Lehman has two other boys, Jonathan and Mario, and a wonderful wife, Tracey, who is supportive of the mini-farm dream but refuses to pull weeds, can vegetables, or wear a bonnet. Dr. Lehman and his family are active in Buddy-Up Tennis and the Columbus Mennonite Church.
