RESEARCH STUDIES
Frontotemporal dementia (FTD) is the second leading cause of dementia in persons under 60 years of age. To assist in early and accurate diagnosis of the disease, with the aim of improving care and therapy options, we are develop new biomarkers and biomarker technologies. A few of our research outputs are noted below:

IMPACT-AD is a Canada-wide study to develop a comprehensive understanding of how Alzheimer’s disease biomarker testing impacts medical and personal decision making, and health care costs. The goal of IMPACT-AD is to inform positive change in the health care system to improve care and support for individuals living with Alzheimer’s disease, and their families.

COVID-19
In response to the COVID-19 pandemic, we leveraged our experience in protein-based diagnostics, including rapid novel assay development and serological testing, to contribute to the fight against COVID-19. A few of our outputs are noted below.
