Roger Diamond is currently doing a PhD at UCT in groundwater, as well as acting as an environmental consultant, specialising in groundwater work, environmental training, environmental law, etc. He has worked in Australia as a geologist and hydrogeologist and in South Africa in waste management and environmental consulting. He has worked for government, private industry, a small consulting firm and now for himself. He also lectures at Cape Peninsula University of Technology. His peak oil interest comes from an environmental angle, especially energy efficiency and related to this he has contributed to Bending the Curve, a local book on climate change, as well as 500 Energy Saving Secrets, an Australian publication. He also writes a blog on the Mail & Guardian's Thought Leader website, called Peak Oil Perspectives.
