Curriculum Vitae

Senior Lecturer


Ph.D. Plant pathology, University of California, Davis, 2005
M.S. Agronomy, Bordeaux, France, 2000

Research Interests

Dr. Petit specializes in evolution and ecology of plant-microbe interactions. She uses grapes in the Northeast US as her model system. 

The Petit's lab focuses on the following themes:
1- Impact of agricultural management on microbiomes
2- Effect of temperatures on flowering time in wild grape species 
3- Variation in resistance to necrotrophic and biotrophic diseases caused by fungi on grape
