Dr. Cieniewicz is a plant pathologist with a research focus on plant virus ecology and virus-vector interactions. At Clemson she directs the Southeastern Budwood Program, associated with the Clemson Peach Team and the USDA National Clean Plant Network, to ensure the supply of virus-indexed peach budwood for the eastern U.S. In addition to the NCPN, she is an active member of the American Phytopathological Society (APS) and the International Council for the Study of Virus and Virus-like Diseases of the Grapevine (ICVG).

 Research Interests

Dr. Cieniewicz is interested in virus ecology, epidemiology, and virus-vector interactions, in particular viruses of specialty crops including peach, grape, strawberry, and others. She is interested in using information gained from virus ecology research to form data-driven management strategies.

 Extension and Outreach

She is a member of the Peach Team at Clemson University, and directs the Southeastern Budwood Program affiliated with the USDA National Clean Plant Network.
