Flora Matheson




Dr. Flora Matheson is a medical sociologist and mental health and addictions specialist. Using a gender lens, she investigates the social determinants of problem gambling and criminal justice involvement.

Dr. Matheson’s work investigating the links between health and criminalization/the justice system have highlighted important risk factors for imprisonment. For example, her research found that young adults (18-28) with traumatic brain injury (TBI) are at increased risk of incarceration and that people experiencing TBI are more likely to incur disciplinary charges.

Dr. Matheson was one of the first researchers in Canada to investigate and measure the strong relationship between problem gambling and homelessness. She and Good Shepherd Ministries co-developed and launched the first gambling-addiction program for people who are homeless.
