Solve for X: Innovations to Change the World

Thanks largely to advances in AI, robots are now capable of things never before possible: picking delicate vegetables, moving heavy goods deftly around a warehouse, making pizzas. But there are still limitations to even the most sophisticated and expensive machines. Replicating human dexterity, for example, remains a surprisingly fiendish challenge. While some experts talk about an imminent “ChatGPT moment” for robotics — one that has the potential to completely transform society — it’s not quite clear when this moment will arrive, or what it will mean when it does. In this episode, we explore how new robot technology is reshaping society, the economy and our understanding of what it means to be human.

The housing crisis is fundamentally a health problem. Decades of research show that people experiencing homelessness spend twice as long in the hospital, cost the healthcare system double and have a life expectancy half that of the average Canadian. In this special episode of Solve for X: Innovations to Change the World, recorded live at a MaRS Morning event, host Manjula Selvarajah sits down with primary care physician Dr. Andrew Boozary to discuss a radical shift in Canadian medicine: treating housing not just as a social service, but as a critical medical intervention. As founding executive director of UHN’s Gattuso Centre for Social Medicine, Boozary shares data-driven insights from his initiatives there: prescribing nutritious food boxes, the launch of Ontario’s first hospital-based homelessness and eviction program and, most famously, the establishment of Dunn House, a permanent supportive housing model that’s proven to be both effective and scalable. Together, Selvarajah and Boozary explore what it takes to dismantle bureaucratic sludge, cut through systematic fragmentation and build a healthcare system rooted in human dignity.

Dr. Andrew Boozary is a primary care physician and the founding executive director of the Gattuso Centre for Social Medicine at University of Health Network (UHN). At the forefront of health equity and public policy, his work focuses on integrating social determinants of health — such as housing, income and food security — directly into patient care. Boozary has spearheaded pioneering social medicine models including Toronto’s modular permanent supportive housing project, Dunn House, establishing crucial healthcare interventions that drastically improve health outcomes while reducing healthcare costs. In 2026, he received a Governor General’s Innovation Award for developing Dunn House.

There are few neurodegenerative diseases as devastating as Huntington’s. It’s sometimes likened to having Parkinson’s, ALS and Alzheimer’s all at the same time, with symptoms that include progressive motor dysfunction, cognitive decline and behavioural change. It’s also hereditary — if a person has the faulty gene that causes the disease, there’s a 50 percent chance their children will have it, too. In the fall of 2025, however, scientists announced that, for the first time, they could reduce the progression of Huntington symptoms using a new gene therapy. While that clinical breakthrough came with several caveats, it also heralded a possible new paradigm for drug discovery. In this episode, we explore how this innovative therapy works and what it could mean for the treatment of other rare diseases. 

Featured in this episode:

Rachel Harding is an assistant professor in the department of pharmacology and toxicology at the University of Toronto and a principal investigator at the Structural Genomics Consortium. Her work on Huntington’s disease has been recognized with major early-career awards, highlighting both scientific excellence and the potential patient impact of her research program.

Brain-computer interfaces (BCIs) have been allowing humans to control objects with their minds for nearly half a century. But in recent years, thanks partly to advances in AI, the technology has evolved dramatically; wearable and implantable devices are now being used to restore speech and movement to stroke survivors, alleviate depression and treat pain. While companies like Elon Musk’s Neuralink grab headlines, a somewhat quieter revolution is happening in Canada, where researchers are using BCI to help a historically underserved population: disabled children. In this episode, we explore BCI’s potential to transform medicine, the knotty ethical questions at its core and how the tech might just bring us closer together.

Featured in this episode:

Dr. Adam Kirton is a professor of pediatrics, radiology and clinical neurosciences at the University of Calgary, where he’s also the director of the BCI4Kids program. He is also the director of the Calgary Pediatric Stroke Program and is a practicing pediatric neurologist at the Alberta Children’s Hospital. He co-founded, and is the CMO, of Possibility Neurotechnologies

Anne Vanhoestenberghe is a professor of active implantable medical devices at King’s College London and director of MAISi, a facility for the manufacture of active implants and surgical instruments, housed at St. Thomas’ Hospital in London, England.

Dion Kelly is a clinical neuroscientist and the co-founder and CEO of Possibility Technologies. Dion and Adam launched the company in 2022 to commercialize their brain-controlled technology, which transforms thoughts into actions. 

Stephanie Sonnenberg and her daughter, Claire, live outside of Calgary, Alberta. Claire was one of the first users of Possibility Technologies’ BCI device, Think2Switch.

The fashion industry has its fair share of dirty secrets, but one of the lesser-known is how much it pollutes our waterways. Every year, garment factories use as much as 2 trillion gallons of water to dye clothes, and most of that water, now filled with harmful chemicals, flows untreated into rivers, streams and lakes. Those pollutants can turn rivers black, harm marine life and cause cancer. Macarena Cataldo, a chemical engineer based in Vancouver, has come up with an ingenious way to remove these contaminants before they even reach the water. In this episode, Cataldo talks to Manjula Selvarajah about the global water crisis, how her technology works and efforts to get major fashion brands to change their ways.

Featured in this episode: 

Macarena Cataldo is the CEO and CTO of Viridis Research, which she co-founded in 2019 to solve various global water challenges by eliminating pollutants from water sources. She has a PhD in chemical engineering, and has spent more than 15 years applying electrochemistry to drinking and wastewater treatment working with the European Space Agency, the Metropolitan Water Company of Turin and others.
