MIST Research Team

The MIST research team, including Dr. Keith Yeates, Dr. Chantel Debert, Dr. Leah Mayo, Dr. Alex Lohman, Dr. Matthew Hill, Dr. Araba Chintoh, and Dr. Alex McGirr pose for a group photo.

Meet the MIST team

The expert MIST team is comprised of a highly-skilled multi-disciplinary group of neuroscientists, physicians, and clinical researchers. Leaders in their respective areas of stress, trauma, concussion, depression and anxiety, post-traumatic stress disorder, and suicide, these experts work together to advance transdisciplinary research, lead public outreach and education efforts, and create impactful opportunities for community engagement. Welcome to the Mental Health Initiative for Stress and Trauma (MIST).

Dr. Matthew Hill, PhD

MIST Research Chair

Dr. Hill is steering MIST to explore how stress and trauma impact the brain, and what can be done to create healthier outcomes.

Dr. Leah Mayo, PhD

Parker Psychedelics Research Chair and Assistant Professor, Cumming School of Medicine, Department of Psychiatry

Full Member, Hotchkiss Brain Institute and Mathison Centre for Mental Health Research and Education

As a human behavioural pharmacologist, Dr. Mayo uses pharmacology (the study of drugs) to understand the brain mechanisms underlying stress and emotional processing — and their contributions to mental health. Her research group, The Psychedelics and Cannabinoid Therapeutics (PaCT) Lab, is particularly interested in discovering the mechanisms and therapeutic potential of psychedelics and cannabinoid-based drugs for patients with stress-related psychiatric disorders like post-traumatic stress disorder.

Dr. Araba Chintoh, PhD, MBBS, FRCPC

Assistant Professor, Cumming School of Medicine, Department of Psychiatry

Full Member, Hotchkiss Brain Institute

Dr. Chintoh is dedicated to improving outcomes for patients who have persistent severe mental illnesses by understanding how psychiatric medications cause side effects and exploring ways to reduce these effects. She is also active in the global sports community – where managing head trauma, such as concussion, is a priority. She consults with international sporting federations to provide technical, scientific, and clinical guidance about athlete welfare issues including brain health and mental health.

Dr. Alex McGirr, MD, PhD, FRCPC

Associate Professor, Cumming School of Medicine, Department of Psychiatry

Full Member, Hotchkiss Brain Institute and Mathison Centre for Mental Health Research and Education

Dr. McGirr’s research aims to improve the lives of individuals with mood disorders such as major depressive disorder and bipolar disorder. Specifically, he uses non-invasive brain stimulation techniques to understand the biology of mood disorders and develop new treatments. One of the main approaches involves transcranial magnetic stimulation (TMS), and his research group is using TMS in conjunction with methods of measuring brain activity to understand how the brain is changed in depression, and then using that information to optimize how TMS can be used as a treatment. The McGirr lab also pursues fundamental science to understand how stress and trauma rewire the brain, with the goal of identifying new treatment targets and ultimately improving lives.

Dr. Alex Lohman, PhD

Associate Professor, Cumming School of Medicine, Department of Cell Biology and Anatomy

Full Member, Hotchkiss Brain Institute and Alberta Children’s Hospital Research Institute

Dr. Lohman studies how the brain and immune system talk to one another, and he explores traumatic brain injuries (TBI) like concussions to better understand how immune cells influence cognition and mental health. He is particularly interested in neuroinflammation (ie. inflammation in the brain) following TBI, and how TBI influences our ability to recover from stress via the endocannabinoid system (our stress recovery system) with the goal of improving patients’ emotional outcomes following TBI.

Dr. Chantel Debert, MD, MSc, FRCPC

Associate Professor, Department of Clinical Neurosciences, Physical Medicine and Rehabilitation Division

Full Member, Hotchkiss Brain Institute

As a physician lead for the Calgary Brain Injury Program, Dr. Debert treats patients with concussion and acquired brain injury in outpatient and inpatient settings. Her research focuses on the pathophysiology, diagnosis, prognosis, and treatment of acquired brain injury with a focus on traumatic brain injury and concussion. The goal of the lab is to explore the underpinning of neurological injury to improve the lives of individuals living with acquired brain injury and concussion. She has a specific interest in evaluating novel treatments and biomarkers in brain injury with a particular interest in fluid biomarkers and transcranial magnetic stimulation.

Dr. Keith Yeates, PhD, ABPP, FCAHS, FRSC

Full Professor, Department of of Psychology

Adjunct Professor of Pediatrics and Clinical Neurosciences

Full Member, Hotchkiss Brain Institute and Alberta Children’s Hospital Research Institute

Dr. Yeates’ research focuses on the outcomes of childhood brain disorders, especially traumatic brain injury (TBI). Much of his research has looked at the psychosocial factors that help account for or modify concussion outcomes — such as mental health —  in children and adolescents. Dr. Yeates is particularly interested in how stress (eg. stressful life events) and pre-existing mental health issues can influence TBI outcomes, because interventions for these factors may result in better outcomes.
