I am an Environmental Plant Biologist specialising in trees and pollution. I studied Biochemistry and Physiology as an undergraduate at the University of Sheffield (1994-1997) an MSc in Environmental Science at the University of Aberdeen (1999-2000) and a PhD at the University of Southampton (2003-2006) investigating the effects of climate change on tree growth.

On completion of my PhD I worked on a number of projects involved with understanding and optimising the sustainable use of trees as a source of bioenergy, and as a natural resource in sustainable urban planning. I have also worked in the teaching profession and the landscape and arboriculture industry.

Teaching Responsibilities

I am the unit leader for two first year units, the Graduate Skills 1 unit and the Marine and Terrestrial Ecology unit. I develop and coordinate the first year tutorial system and contribute to tutorials across all three years. I am the first year induction coordinator and have a strong interest in the role the tutorial system can play in helping students with the transition to a university education. I also contribute to the teaching of the following units: first year Experimental Biology; second year, Community Ecology including a residential field trip, and Marine Organisms and Ecosystems; and in the third year Aspects in Terrestrial Ecology and Evolution. 


The main focus of my research is to develop the understanding of how plants, in particular trees, respond to pollution and to changing environmental conditions. I use techniques to study plants that range from the molecular, to the plant scale, and up to global scales. Specific interests include:

  • The effects of climate change on plant growth and function.
  • Understanding and optimising the use of urban plants in managing urban air pollution.
