Research summary

Most of Dr. Riddell’s research is done in collaboration with programs and communities. She enjoys working with clinicians, mental health service users, and Indigenous peoples to deepen our understanding of wellness, design programs to promote wellness, and improve access to these programs. Some of her ongoing research explores the role of toxins, such as fluoride and lead, in the development of health conditions such as attention deficit hyperactivity disorder and thyroid dysfunction. Her ultimate aim is to prevent mental health difficulties by advancing human rights and environmental justice.


Dr. Julia Riddell is an assistant professor in clinical health psychology at the University of Manitoba. She is also a clinician-scientist who also works as a consulting psychologist in the Interlake-Eastern Regional Health Authority providing psychological assessment and treatment for children, adolescents and adults.

In the past, she has worked in wilderness therapy and in private practice offering Dialectical Behaviour Therapy (DBT).

She cares deeply about making mental health services accessible to everyone and is currently working with a team of psychologists to evaluate a modified version of DBT that is being delivered across Manitoba.

Dr. Riddell is grateful for the time she has spent being involved in the Walking the Prevention Circle Project, a SSHRC-funded partnership between Indigenous communities and the Canadian Red Cross. This project allowed her to develop relationships with community members in Arviat, Nunavut, who invited Dr. Riddell to co-create a program evaluation of their Young Hunters program. Young Hunters is a land-based program that teaches cultural values to Inuit youth and promotes food sovereignty in the community. In her program of research, she continues to co-create and evaluate innovative mental health and wellness programming, and consider how to improve access to mental health services.

Dr. Riddell is passionate about teaching and learning. She currently teaches a range of therapeutic modalities and clinical skills to medical students and community mental health workers. In the past, she has taught courses in psychology and global health at the undergraduate level.
