Visiting staff

The GSI has benefited from working in collaboration with various Visiting Staff from across a range of academic disciplines and vocational backgrounds. Visiting status is conferred by the Faculty, and all staff sit within one of our three key research themes.

Prof Victor Anderson works on the politics and economics of sustainability. Currently his main project is contributing research on political institutions for the Centre for the Understanding of Sustainable Prosperity (CUSP). He is also investigating the implications of the concept of "natural capital" as part of the Debating Nature's Value network.

Victor has previously worked as an economist for the UK Sustainable Development Commission, a government advisory body in Whitehall, and for the World Wildlife Fund, an environmental NGO. He has worked at the House of Commons as a researcher for MPs, and was an elected politician for three years as a member of the London Assembly, also being appointed Environment Advisor to the Mayor and a Board member of the business-led London Development Agency. He is the author of two books, ‘Alternative Economic Indicators’ and ‘Energy Efficiency Policies’, and hopes that his work on CUSP will result in the third.

Arianoutsou).

Bob Evans

Head shot of Bob Evans

In the 1960s Dr Robert (Bob) Evans counted sheep for two years in the Peak District: there were too many of them and they created bare soil and caused erosion. Bob came to Cambridge in late 1968 to research the use of remote sensing techniques for mapping soils. So started a lifetime of monitoring soil erosion in the UK. Much of the work on erosion in Britain was initiated by a short paper published by Bob in 1971. In the mid-1980s he organised a scheme monitoring water erosion of arable land in 17 localities in lowland England and Wales. Because, uniquely, there has been much monitoring of erosion in farmers’ fields in Britain, we can compare that information with modelled information and have discovered that models overstate erosion. 

Bob has been an independent consultant since the late 1980s, most of that time also being a Research or Visiting Fellow in Cambridge Universities. He has worked with government departments, the Environment Agency, a major NGO, companies, farmers and the NFU and on university research contracts, as well as being an expert witness in court. His work in the uplands helped bring about changes in national grazing policy and he was an advisor to the Royal Commission on environmental pollution when it produced its report on Sustainable Use of Soil in 1996. Bob now considers that soil erosion, although a problem over the long-term (in causing the loss of a resource) and short-term (causing pollution of water courses by sediment), nutrients and pesticides transported from the land in runoff is the more pressing issue.

John Stevenson

Dr John L. Stevenson was awarded a Ph.D. in Electrical Engineering, from the Imperial College of Science and Technology - then a part of the University of London - in 1973. John worked on technical and commercial assignments for British Telecom (1970-1978) and at INTELSAT (Washington D.C., 1979-1999), before becoming CTO of Orblynx Inc. and Director of Systems Planning for Astrolink LLC, both in the U.S. He has long held an interest in issues of sustainability and their international implications, all based upon a review of the original Limits to Growth research undertaken at M.I.T. and broadcast in circa 1980.

Over the past decade John has undertaken two lines of professional consultancy work, focused upon wireless telecom systems, and upon photographic image processing. In the first case, he specialised in the development of business case modeling and analytics. In the latter activity he is currently affiliated with Adobe Systems Inc., in the development of their Photoshop software product. He was invited to join the GSI as a Visiting Fellow in 2016, due to his skills in systems dynamic modelling and data interpretation.

Nick Tatchell

Head shot of Nick Tatchell

Nick Tatchell joined the GSI in May 2019. He is currently a Senior Director at Willis Towers Watson, a global professional services firm. His background in Organisational Psychology led him into a career as an HR consultant, working with large UK and global clients on projects typically focusing on employee motivation, employee engagement and organisational culture.

He has consulted at Board level on how to measure and change company culture, identify drivers of employee motivation, and evaluate the behavioural drivers of business performance. A project for a global financial services organisation established a programme to measure its culture, delivering a regular series of metrics to its Board, and helping to create a more transparent and inclusive work environment. A project for a global law firm measured the impact of its programme to improve the retention of its female associates.

Nick’s experience in developing a deep understanding of behavioural drivers within organisations has combined with his fast-growing interest in issues of sustainability. His work at the GSI will therefore seek to identify the challenges associated with creating new patterns of pro-environmental personal behaviour, within the context of an organisation’s cultural norms and commercial priorities. It is expected to draw on and combine insight from the disciplines of Behavioural, Environmental and Organisational Psychology.
