There's power in shining a light on an invisible injury.

That's what Dr. Ruth Lanius has heard from the patients she's treated for post-trauma stress disorder (PTSD). Working with civilians, military members, first responders and refugees, the internationally recognized researcher is exploring new and effective ways to treat PTSD. In this episode of The Catalysts, Dr. Lanius shares what she knows about PTSD and what's yet to be discovered.

Dr. Ruth Lanius is a Professor in the Department of Psychiatry at the Schulich School of Medicine & Dentistry, Western University. She holds the Harris-Woodman Chair in Psyche & Soma.

The health of our planet requires a solution that bridges perspectives, knowledges and people.

It's a solution that Nicole Redvers, DPhil, ND, has promoted at regional, national and international levels, working to advocate for the inclusion of Indigenous perspectives in both human and planetary health research and practice. In this episode of The Catalysts, we catch up with Redvers to learn about her prescription for planetary health.

Nicole Redvers, DPhil, ND, is a member of the Denı́nu Kų́ę́ First Nation (Northwest Territories, Canada), and is an Associate Professor, Western Research Chair, and Director of Indigenous Planetary Health at the Schulich School of Medicine & Dentistry at Western University.

When it comes to predicting your health, the answer often lies in your DNA.

That's according to Dr. Rob Hegele, whose life's work has led to numerous breakthroughs for patients combatting cardiovascular disease. In this episode of The Catalysts, we catch up with the 2026 Canadian Medical Hall of Fame inductee to learn about reading DNA, treating high cholesterol, witnessing groundbreaking research and the art of curiosity and discovery.

Dr. Rob Hegele is a Distinguished University Professor in the Departments of Medicine (Division of Endocrinology) and Biochemistry at the Schulich School of Medicine & Dentistry. He is a Scientist at the Robarts Research Institute, where he serves as Director of the London Regional Genomics Centre.

He is also the holder of the Edith Schulich Vinet Chair in Human Genetics, the Jacob J. Wolfe Distinguished Medical Research Chair in Human Gene Function and the Martha G. Blackburn Chair in Cardiovascular Research.

What if we could teach the immune system to fight cancer? Dr. Carl H. June pioneered the bold ideas behind CAR T-cell therapy, a breakthrough that is transforming cancer treatment and holds the potential to reshape care for millions. In this episode, he reflects on a remarkable career that has spanned the Vietnam War, the HIV epidemic and the rise of modern immunotherapy. He shares how curiosity has driven his work, and why he remains a champion for science in an era when it is increasingly under threat. Dr. June is the 2025 J. Allyn Taylor International Prize in Medicine laureate.

Breast cancer is the most common cancer in Canadian women, with 1 in 8 women facing a diagnosis in their lifetime. It's a complex foe, shaped by biology and lifestyle, made difficult by invasive treatments and cumbersome diagnostic techniques.

In this episode, Dr. Ana Lohmann, a medical oncologist and scientist at Western University's Schulich School of Medicine & Dentistry, discusses how this complexity is being met head-on. Her research explores how obesity and metabolism shape cancer diagnosis and recurrence, and how lifestyle, access to care and social inequities influence outcomes. She also discusses emerging tools like liquid biopsies and the growing focus on survivorship and quality of life.

What if your body already held a secret weapon to beating cancer? Dr. Mansour Haeryfar, PhD, is tapping into MAIT cells — a rare type of immune cell that can be supercharged with bacterial molecules to hunt down tumours. His research suggests these cells could form a basis for powerful, universal therapies that work across patients. In this episode, he'll reveal how this cutting-edge science could transform cancer treatment and how the inspiration to fight against malignancy came from an unexpected source.
