Kathy is an agri-environmental chemist who joined the University in 1995 and established AERU soon after. Kathy became a Professor in 2014. She is now (almost) retired working part-time within AERU.
Kathy's main areas of interest include environmental management of agriculture, horticulture and land-use, in particular environmental pollution from chemical inputs and the impacts arising from agricultural processes taking a whole farm perspective. Historically, Kathy's work covered a wide spectrum of topics including pesticides, nutrients, waste and resources and biodiversity, particularly with respect to climate change and rural development. She now focus’s just on pesticides and their risk assessment.
Kathy is a Fellow of the Institute of Analysts and Programmers (FIAP) and a Member of the Institute of Environmental Management and Assessment (MIEMA). She is also the UK Editor of the Elsevier scientific journal ‘Agriculture, Ecosystems and Environment’.
Qualifications
Kathy's first degree in environmental chemistry with computer science was awarded by the Council for National Academic Awards (CNAA), and her PhD in agricultural best practice and was awarded by the University of Hertfordshire.
Previous employment
Before joining the University of Hertfordshire, Kathy spent 23 years at Warren Spring Laboratory and 1 year in Industry working as an Environmental Manager.
