Research Scientist

I am a molecular plant biologist and virologist who studies viral diseases of tree fruits, grapevines, small berries, and tomatoes.

Current research and/or projects

I employ molecular biology and genomics approaches to study the interactions between plant viruses and fruit crops. Major research areas include approaches to surveying viral extent and diversity in agricultural settings, studying the molecular nature of viral infection in stone fruits and tomatoes, and development of resistance to major viral diseases in stone fruits and tomatoes.

Research and/or project statements

Current projects:

-Plant virus surveillance using bees

-Investigating the cause of tree fruit decline

-Development of resistance to Plum pox virus in peach

-Development of resistance to Tomato brown rugose fruit virus

-Genomics of grapevine viruses
