Tylka joined Iowa State University in February 1990.  He currently is a professor in the Department of Plant Pathology and Microbiology. Activities in Greg Tylka's program at Iowa State University focus on the biology and management of plant-parasitic nematodes, with major focus on the soybean cyst nematode (SCN), Heterodera glycines.  Current research includes study of SCN-resistant soybean varieties, effects of nematode-protectant seed treatments, and interactions between SCN and insect herbivores.
