A simple bio you can use:
Justin Podur the author of Haiti's New Dictatorship (Pluto Press 2012). He has contributed chapters to Empire's Ally: Canada and the War in Afghanistan (University of Toronto Press 2013) and Real Utopia (AK Press 2008). He is an Associate Professor at York University's Faculty of Environmental Studies.
What are these speaking engagements? In recent years I have spoken on the following topics:
-The Democratic Republic of the Congo (DRC)
-Colombia & Venezuela
-Canadian foreign policy (and indigenous issues)
-Israel/Palestine (and Middle East politics more generally)
-Afghanistan, Pakistan, India
-Globalization, economics, imperialism & anti-imperialism
I can talk on most things that I write about - these are the talks that I get invited to do. If there is an audience that will benefit from it, I will speak for expenses (having read George Monbiot's book, "Heat", I increasingly think traveling long-distances to give talks is ecologically unsound and prefer to speak around where I live, and I guess I would encourage others to book speakers who are local). I currently have an income from non-political work, so I seek honoraria and donate them to cash-strapped social justice organizations (usually OCAP).
