Dean Meason



Dr Dean Meason is a tree ecophysiologist who has worked with a number of different temperate and tropical forest species to provide a mechanistic understanding to forest management. His expertise with eucalypts and coast redwood is well recognised nationally and internationally. His focus at Scion is to take a systems biology approach to understand the spatial and temporal mechanistic drivers of wood formation and wood quality, growth, resource use, and silviculture at different scales under current and future climates for the forest industry and its implications for other land uses.
