Professor, School of Integrative Plant Science Plant Pathology and Plant-Microbe Biology Section Cornell AgriTech
Marc was born and raised in Alsace, France. He received his Master’s and PhD degrees from the University Louis Pasteur in Strasbourg, France. His program emphasizes translational research on virus diseases. Primary research goals are to (i) investigate the nature of virus populations to better understand disease spread, (ii) elucidate the interface between viruses, their vectors, and plant hosts to characterize spread and pathogenicity, and (iii) explore innovative approaches for disease management. Extension efforts of the Fuchs program focus on the identification of emerging virus diseases, and the dissemination of information on the biology and ecology of virus diseases.
Virus diseases of fruit and vegetable crops
Plant virus-insect vector interactions
My program emphasizes translational research on virus diseases of vegetable and fruit crops. Primary goals are to determine the genetic variability of virus populations for advancing our understanding of virus spread, and to study interactions between viruses, vectors, and plant hosts with the aims of developing robust detection methodologies, and implementing innovative approaches for crop improvement.
Outreach and Extension Focus
The extension component of my program focuses on the (i) identification of virus diseases of vegetable and fruit crops, in particular emerging diseases, (iii) dissemination of information on the biology and ecology of viral diseases to extension educators, growers, regulators, horticulture inspectors, and agriculture service providers. Efforts are also directed to a grape certification program and service activities for assisting the management of virus diseases of vegetable and fruit crops.

Leafroll disease, a virus spread by mealybugs, damages grapevines, reduces yield and alters grape quality – all of which can detrimentally affect wine quality and cost growers tens of thousands of dollars per hectare. There’s no cure for...
