My research program addresses critical needs for sustainable management of grapevine fungal and oomycete diseases. Our collaborative research aims to develop new grape varieties that are healthy, delicious, and disease resistant, exemplified by the VitisGen project that I co-lead.
In the process, we are analyzing billions of data points to better understand the biology of host and pathogen co-evolution and how their DNA sequences determine which will prevail: the grapevine or the fungus. This basic scientific research using cutting-edge genomic tools enhances traditional breeding approaches, as we develop eco-friendly disease resistance that will last for future generations.
