I am an industrial ecologist in the School of Environment, Enterprise & Development in the Faculty of Environment.

Following 15-years of consulting in the private sector, I now research management approaches to build a circular economy to meet the needs of people today and for future generations. This includes making commodity materials like steel and concrete more sustainable resources -- and ensuring responsible access to materials like tungsten and tantalum that are critical for a low-carbon society. 

Since 1999 I have taught at Waterloo on environmental management, corporate responsibility and sustainable development.
