Dr. Heckman teaches at the University of Manitoba's Robson Hall law school. His research interests include administrative and constitutional law, human rights law and refugee law.

His recent publications have focused on the influence of international human rights norms on states' domestic legal systems. Heckman's Osgood Hall dissertation explored the gap between procedural rights guaranteed to refugee claimants by international human rights treaties and the domestic procedural protections provided claimants under the Canadian, American and Australian systems for refugee protection decision making.

Heckman obtained an LL.M. in administrative law from Queen’s University in Kingston, where his thesis investigated the gatekeeping powers of Canadian human rights commissions.
