Cryopreservation of temperate recalcitrant seed
Study of the fundamental basis of desiccation and low temperature stress tolerance in recalcitrant seed tissues of temperate species in order to optimise their cryopreservation.
My research in the Comparative Seed Biology group aims to reveal the fundamental basis of desiccation and low temperature stress tolerance in seeds, particularly in relation to successful cryopreservation. In addition to studies on recalcitrant seeds (e.g. oaks), I am interested in the variation in longevity in plant propagules, from fern spores as a unicellular model to more complex systems. Often these studies involve making structural and biophysical determinations. I also carry out teaching and training activities for staff and supervise undergraduate, MSc and PhD students.
