Research

Dr. Ristaino works on the population genetics of historical epidemics of the pathogen that caused the Irish famine Phytophthora infestans and studies the population structure and epidemiology of modern day late blight outbreaks.  Her lab is interested in the impact of migration, recombination and hybridization on the evolution of Phytophthora species.  Her work has tracked migrations of P. infestans from its ancestral home in the Andes to the US and Europe. She developed pioneering research techniques for use of 150-year-old historic herbarium specimens to track epidemics. She was also part of the team that sequenced the first genome of P. infestans. Her recent work with collaborators has used next generation sequencing to study historical outbreaks.  Her lab also manages the disease surveillance network called USABlight.org. This system records late blight outbreaks, sends disease alerts to growers, and provides decision support tools for managing disease. She has recently developed novel VOC sensor-based technology for detection of late blight. She also conducts Phytophthora molecular diagnostics workshops globally. Her lab also has described new species including Phytophthora andina and Phytophthora acaciae and developed a Lucid-based taxonomic key. Dr. Ristaino was named a National Academy of Sciences Jefferson Science Fellow in 2012 and has worked on a range of emerging plant diseases that impact global food security with USAID. She currently directs a new faculty cluster at NC State on “Emerging Plant Disease and Global Food Security”. She was awarded a Fulbright Research Scholar Award in 2017 at the University of Catania in Sicily. In 2020, she was elected a Fellow of the American Phytopathological Society. Dr. Ristaino’ research impacts the science of plant pathology, epidemiology, population genomics, food security and science policy (https://ristainolab.cals.ncsu.edu).
