Stephen Wyka

Ph.D. Student, USDA Pre-Doctoral Fellow


Stephen's overall goal is to better understand the evolutionary and lifestyle history of Claviceps purpurea with its grass hosts by combining greenhouse, field surveys, and comparative genomic based approaches. Genomic research focuses on identifying genes under selection pressure that can help us understand the successfulness and broad host range of C. purpurea compared to other claviceps species that have very narrow host ranges and are significantly more destructive to their hosts. He can also been found at
