I have spent most of my scientific career, focusing particularly on plant-nematode interactions.I gradually developed my research activities, introducing molecular genetics and genomics research as the basis of studies of plant-nematode interactions.

I use a multidisciplinary approach that have broadened over the years, from my initial studies focusing principally on the nematode, to comparative genomics and approaches based on plant genetics. My research activities now focus on several complementary aspects of plant nematode interactions and the root-knot nematode (RNK) genus Meloidogyne, which I have chosen to develop as a model organism for research studies.
