Research

· Currently, my main research focus is the use of stable isotopes (carbon and oxygen) as integrative measures for plant water use and water use efficiency. This involves 1) basic research to improve the understanding of the underlying mechanisms determining stable isotope composition in plants and their relationship with physiological processes (Kodama et al. 2008, Gessler et al. 2009, Ferrio et al. 2009), and 2) applied research to develop applications of stable isotopes to assess genetic and environmental variability in water relations of cereal crops and Mediterranean tree species (Ferrio et al. 2003, 2007, Ferrio and Voltas 2005, Tambussi et al 2005, Voltas et al. 2009).
