Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Meta-bifurcation analysis: glorified number-crunching for dynamical systems analysis

Abstract: In classical dynamical systems analysis, bifurcation theory helps classify the different types of behaviour which occur as we vary model parameters. Although very successful for relatively simple models, this approach has little use for the analysis of physiological models, which typically have many parameters with a large range of admissible values.\r\nI will explain how automated bifurcation analysis of many parameter sets leads to an analysis of robust behaviour, pervasive to the model with all parameter uncertainty considered. As an example, I will present the meta-bifurcation analysis of a mean-field model of human electrocortical activity. This approach unveils non trivial correlations between model parameters and the response to introduction of anesthetic agent, with possible implications of monitoring of anesthesia.
