My lab works on emerging plant diseases that threaten global food security. A major focus of research is to understand the factors that contribute to disease emergence including the epidemiology and population genetics of Oomycete plant pathogens in the genus Phytophthora. Phytophthora infestans caused the Irish potato famine in the 1840s, and is a reemerging threat to global food security. We study the population genetics and migrations of both historic and present day strains of the pathogen. My lab was part of a multi-investigator group that sequenced the genome of the pathogen. We are now using the genome sequence to develop novel strategies for managing disease in the field. Our team has developed a web portal called USAblight.org that can be used to track recent outbreaks of disease using geospatial analystics. We also work on other pathogens of tropical crop plants including black Sigatoka on banana, downy mildew of tobacco, soilborne fungi and coffee rust that are threats to global food security. Dr. Ristaino serves as the director of the “Emerging Plant Disease and Global Food Security” cluster at NC State, has served as a Jefferson Science Fellow for the US Department of State and received a Fulbright European Research Scholar Award to work with the University of Catania on late blight in Italy in 2018. In 2020, I was elected a Fellow of the American Phytopatholoical Society in August 2020 and named a AAAS Fellow in November, 2020. In 2022, Dr Ristaino will serve as a Fulbright Scholar in the Republic of Ireland.
Plant diseases don’t stop at a nation’s borders and miles of oceans don’t prevent their spread, either. That’s why plant disease surveillance, improved plant disease detection systems and predictive plant disease modeling – integrated at the global scale – are necessary to mitigate future plant disease outbreaks and protect the global food supply, according to a team of researchers in a new commentary published in Proceedings of the National Academy of Sciences.
See local CBS17 news on the PNAS paper and Washington Post report “Plant Pandemics and how they could endanger our food supply. Scientists sound alarm on growing menace”.
In many contexts and times, diseases have reshaped life, whether it be human life, animal life or plant life. Here we share a podcast interview of ongoing research about the consequence of plant disease. I gave a podcast on the consequence of plant diseases and the Irish Potato famine. In this podcast, I share own experience with plant pathology, her global travels to track outbreaks and then talks about my efforts to understand the history of the potato famine and why it is relevant to controlling emerging pathogens of all kinds today.

Outbreaks: Tackling Emerging Plant Diseases that Threaten Food Security January 10, 2020, 1-7PM The Emerging Plant Disease and Global Food Security Cluster held a symposium in January to highlight the innovative research of the cluster team. The cluster works to improve both local and global efforts to manage emerging pests and pathogens that threaten crop production and lead to food insecurity. NC State has a strong history in conducting international agricultural research and outreach. Many emerging “armed and dangerous” plant diseases and pests threaten US and global agriculture and reported outbreaks have become more severe with trade and changing climate. See the EBD Program here.
