Research

I am a grapevine physiologist with interests in both basic and applied research geared up to address the industry goals. My particular area of research is integrative plant physiology and plant anatomy, basically utilizing the knowledge of structure-function relationships to improve vine health and fruit quality. More specifically, our lab investigates ampelography and cultivar identification, water relations of grapevine and berry, developmental anatomy of grape berry, physiological and structural adaptations to water stress, and hydraulic architecture of grapevine and berry. We investigate the above research goals using light, confocal and electron microscopy in combination with contemporary approaches adopted to study the physiology of the plants.

Current Projects

  • Causes and symptomatology of grape berry shrivel
  • Anatomical basis of 2,4-D damage
  • Extended ripening and berry composition
  • Histology of grape berry
  • Ecophysiology of water stress (drought)

Teaching

My teaching activities include recruiting students, advising students interested in viticulture and enology, and teaching classes encompassing viticulture, horticulture, and biology.
