Julien Levy

Julien Levy, Ph.D., is a Researcher in the Department of Horticultural Sciences at Texas A&M University since 2009. He holds a B.A. in Physiology, Genetics, and Molecular Biology from University Paul Sabatier Toulouse II, followed by an M.S. in Molecular Genetics and Cellular Biology and a Ph.D. in Plant Science (Molecular and Cellular Biology) from the same institution, with affiliations to CNRS-IBCG and INRA-LIPM. His research focuses on understanding molecular mechanisms governing plant-microbe-insect interactions, employing molecular biology, plant breeding, and genetics to enhance food production and security.

Levy’s work emphasizes the role of 'Candidatus Liberibacter solanacearum' (Lso) and its vector, the psyllid Bactericera cockerelli, in plant diseases such as zebra chip. His studies explore haplotype-specific effects of Lso on host plants, effector proteins, and defense responses. He investigates long-term impacts of psyllid infestations and pathogen infections on plant physiology and gene expression.

Key research themes include developing diagnostic methods (e.g., LAMP PCR), analyzing transcriptomic responses, and identifying genetic tolerance in crops. His contributions bridge fundamental molecular mechanisms with applied agricultural solutions, aiming to mitigate crop losses from emerging diseases.
