I am a third year PhD student in the Institute of Atmospheric and Environmental Sciences at the University of Edinburgh. I first joined the University of Edinburgh in 2002, when I attended the MSc in Forest Ecology and Management. Currently, through my thesis I am trying to investigate the underlying reasons of the age-related decline in forest productivity. The need of a better understanding of the physiology of trees of different ages has recently been stressed. Further information is available in the research link.
