Greg Tylka

Dr. Greg Tylka is a professor in the Department of Plant Pathology and Microbiology at Iowa State University with extension and research responsibilities for management of plant-parasitic nematodes. The focus of Dr. Tylka's research program at Iowa State University is primarily the soybean cyst nematode (SCN), Heterodera glycines. Current research includes study of SCN-resistant soybean varieties, effects of nematode-protectant seed treatments, and the effects of cover crops on SCN biology and management. He also serves as director of the Iowa Soybean Research Center at Iowa State University.

Activities of the Tylka laboratory are primarily funded by the soybean checkoff, through grants from the Iowa Soybean Association, the North Central Soybean Research Program, and the United Soybean Board.

Dr. Tylka was born and raised in southwestern Pennsylvania, just outside of Pittsburgh. He attended California University of Pennsylvania, where he earned his bachelor's degree and master's degree in biology. He then attended the University of Georgia, where he earned his doctoral degree in plant pathology.

Dr. Tylka joined Iowa State University in February 1990.
