Here’s a bold statement: Some of the most groundbreaking medical advancements aren’t coming from doctors—they’re coming from the labs of researchers like Molly Shoichet, a cell and tissue engineer at the University of Toronto. But here’s where it gets controversial: Shoichet abandoned her dream of becoming a doctor to focus on something even more transformative—improving medicine itself. And this is the part most people miss: her journey began with a simple polymer, a discovery that shifted her entire career trajectory.
During her undergraduate years at MIT, Shoichet encountered polymers—large molecules made of repeating units found in everything from proteins to plastics. 'I thought that was the coolest thing,' she recalls. This fascination led her to pursue a PhD in polymer science and engineering instead of medical school. Fast forward to today, and Shoichet is a University Professor and the Pamela and Paul Austin Chair in Precision and Regenerative Medicine at U of T, where her work spans spinal cord injuries, blindness, cancer, and more. Her secret weapon? Hydrogels—squishy, water-absorbing polymer chains that mimic human tissue and can deliver medications to hard-to-reach areas like the brain and retina.
Here’s the bold part: Shoichet compares her work to FedEx, saying, 'We focus on the packaging to get therapeutics where they need to be, when they need to be there.' This analogy might sound simple, but it’s revolutionary. For instance, her collaboration with Cindi Morshead has led to a stroke treatment that bypasses the injury scar to promote brain repair—a breakthrough now driving Chase Biotherapeutics. Similarly, her hydrogel-based treatments for retinal diseases, developed with Valerie Wallace and Derek van der Kooy, are being refined by Synakis, a spinoff company.
But it doesn’t stop there. Shoichet’s hydrogel technology is also tackling post-operative pain. Through AmacaThera, her team has developed a gel that releases pain medication directly at incision sites, potentially replacing addictive opioids. And if that’s not enough, she’s using hydrogels to study how cancer cells invade tissues—a problem so complex it’s kept her curious for decades.
Here’s the question that sparks debate: Is academia doing enough to tackle the hardest challenges in medicine? Shoichet’s answer is a resounding yes, but she believes researchers must lead the charge. 'If we in academia don’t go after the hardest challenges, nobody else will,' she asserts. Her impact extends beyond the lab; she’s founded multiple startups, won countless awards, and even served as Ontario’s first (and only) chief scientist. Yet, she remains grounded, celebrating her PhD graduates by hanging their lab coats in her lab—a tradition that honors their contributions.
Former student Daniela Isaacs-Bernal credits Shoichet for teaching her to synthesize complex ideas into understandable concepts, a skill she now values in her industry role. As Shoichet enters her fourth decade at U of T, she balances her relentless pursuit of innovation with a love for ballet, hiking, and open-water swimming. But don’t expect her to slow down anytime soon. Her work isn’t just about solving problems—it’s about inspiring the next generation to ask bigger, bolder questions.
Thought-provoking question for you: Do you think academia is doing enough to tackle the hardest medical challenges? Or is it up to researchers like Shoichet to push boundaries? Let’s discuss in the comments!
