About Me

I am an interdisciplinary social scientist who studies the intersection between environmental governance and the global economy.

I am Canada Research Chair in Economy and Environment and Assistant Professor in the School of Environmental Studies and Department of Global Development Studies at Queen’s University. 

One area of my work has examined investor-state disputes concerning environmental regulation that are brought to international arbitration under bilateral and regional investment agreements.

Another area of my research focuses on green stimulus/green recovery programs and efforts around the world to launch a Green New Deal (see dedicated research website:

Routledge Handbook on the Green New Deal

In recent years, the Green New Deal has moved from relative obscurity to front and centre of policy discussions and public debates about how to respond to the climate crisis. It has been credited with radically changing the nature of the conversation on climate change and with re-energizing the environmental movement at a critical time. All Green New Deal proposals share an emphasis on the need for governments (rather than markets) to lead the energy transition. However, they differ in other respects. This Handbook analyses the fundamentals underlying all Green New Deals as well as exploring national and regional variations.
