Research area: Terrestrial vegetation, especially ecological and physiological modelling
Dr. Andrew D. Friend

My PhD research looks at the global scale interactions of environmental variables and the structure and functioning of vegetation. I am particularly interested in mortality processes by which carbon is transferred from living biomass to dead biomass and is eventually either return to the atmosphere or incorporated into soils. How do mortality rates vary at large scales? Are there particular environmental drivers behind these variations? These are only two out of a plethora of questions my research addresses.

Research Interest

My research interest is in plants and agriculture in the largest sense. While I often use modelling approaches, I love experiments and field work. I generally prefer vascular plants, but will not discriminated against mosses or algae if the project grabs my attention.
