Antony Chum
Antony Chum is assistant professor in the School of Kinesiology in the Faculty of Health and CRC Tier II in Population Health Data Science. Deaths and diseases of despair are those that are preventable, and they include substance-use disorders, suicides and overdose deaths. In 2019, they accounted for approximately 30 per cent of deaths for Canadians aged 15 to 49 years. Research into the causes of despair and strategies to reduce it may lead to substantial improvements in quality of life and life expectancy.
Chum is establishing a national hub that will use population health data science to study the causes of – and solutions for – deaths and diseases of despair. He and his research team are investigating the epidemiology of deaths and diseases of despair as a unified phenomenon. They are also examining the role of follow-up care in preventing suicides, overdoses and substance-use disorders as well as evaluating how public policies can reduce these self-inflicted deaths and diseases.
Liya Ma
Liya Ma is CRC Tier II in Cognitive Neurophysiology and an assistant professor in the Department of Psychology in the Faculty of Health. Human brains are generally flexible enough to adapt to changes in the world around us. But, reduced flexibility in thinking and behaviour is common among patients who suffer from certain neuropsychiatric disorders, such as schizophrenia or autism.
Ma and her research team are investigating how neurons in the brain enable flexibility in decision-making. The research team is exploring how neural communications can support cognitive flexibility in non-human primates. To do this, they are monitoring primates’ neuronal activities during tasks and manipulating the neurons’ activities to identify the roles that specific brain regions play in terms of cognitive and behavioural flexibility. Ma and her team are also using experimental data to design mathematical models for cognitive flexibility and identifying the pathological changes that lead to brain damage. Their research could shed light on new ways to treat neuropsychiatric disorders.
