Anna’s research explores immigration penality in Canada. She is the author ofSecuring Borders: Detention and Deportation in Canada (UBC Press, 2005). She has carried out a major study of frontline border control in Canada and has published findings that interrogate the law/discretion binary, the enabling effects of administrative discretion, racial profiling and the production and transmission of heterogeneous risk knowledges on the frontline and in the courts. Anna has also examined the introduction of bordering technologies that mobilize vigilant citizens and communities in Canada, such as the CBSA Most Wanted List. Her current research explores the mechanisms of administrative discretion, jurisdiction and scale in relation to criminality-based deportations from Canada, paying close attention to the effects of judicial discretion.
