Episode 2 – Dr. Beate Sander on the economics of infectious diseases and guiding public health policy during the COVID-19 pandemic
Air Date: October 19, 2021 | Length: 47:21
It was Canada’s worst fear in March 2020 — COVID-19 reached the great white north. With increasing case counts and hospital burden throughout the country and in Ontario, government officials were looking to lean on healthcare economists to predict the impact of the pandemic. Dr. Beate Sander’s research highlights the importance of epidemiological modelling and how it guided public policy in Ontario. With the ever-changing data from around the world, her team highlighted the importance of certain measures to stop the spread. She discusses how the pandemic affects certain populations disproportionally. Plus, she expresses the need for better public data infrastructures, reporting, tracking and analytics to be well prepared in the future.

Episode 3 – Dr. Taufik Valiante invents computer chip designed to monitor and stop epileptic seizures
Air Date: November 3, 2020 | Length: 52:27
What if a tiny computer chip could be implanted into the brain to look out for epileptic seizures and then stop them before they ever occur? Sounds like science fiction – and yet – Dr. Taufik Valiante’s lab at the Krembil Research Institute has done just that. His chip is called ‘NURIP’ – the acronym for neural interface processor and it’s inspiration came from the engineering concept of control theory and applied to the brain.NURIP “is this idea that we can modulate, alter brain activity in a way to push the brain away from states that are bad for it, and epilepsy is just an example,” explains Dr. Valiante. NURIP is entering the animal model testing phase and if successful would be a game changer in the treatment of epilepsy.
