Area of Specialization

Biology and control of viruses and graft-transmissible agents of grapevines, stonefruits, and walnuts.

Research

Carries research on the identification, detection and biology of viruses and graft transmissible agents grapevines, stonefruits, and walnuts. Interests include developing sensitive and cost-effective diagnostics, and applied and biotechnological approaches to sustainable management of diseases, molecular virology, and use of plant virus vectors for genomics.
