He has authored more than 150 scientific research papers, a book about the Boat People entitled "Strangers at the Gate", and is co-editor of the forthcoming "Immigration, Ethnicity, and Health". He also conceived and produced a radio program on immigration in Canada which was aired from 1999 to 2000 in Ontario and Alberta, as well as a version for Canadian students, "Strangers Becoming Us", to be used in the classroom, seeking to move his research from the realm of scientific research to policy debate. "Strangers Becoming Us" is still in use in all public elementary and high schools in Canada.
