Using data science to better understand social inequalities in child and youth mental health. Analysing astrophysics data to shed light on the theory of evolution. Using machine learning techniques to assess brain injuries.

Nine McMaster graduate students have been awarded fellowships from McMaster’s MacDATA Institute to pursue these and other multidisciplinary projects that are using data science approaches to provide new insights into a number of areas of research.

Throughout the eight-month fellowship, students will work with McMaster faculty on projects that apply data analysis, collection and curation methodologies to diverse areas of research, including projects related to health care, health policy, finance, biology and linguistics, among others.

“Researchers can get at information they couldn’t get at before because of the richness of the data and the data science methodologies that are being developed,” says Paul McNicholas, director of the MacDATA Institute. “This fellowship provides students with a unique opportunity to work with researchers in other disciplines to apply these methodologies and extract insights from data that might they might not otherwise be able to extract.”

The fellowship is intended to provide students with practical experience, and to facilitate an exchange of knowledge in data science across Faculties. Fellows will be co-supervised by at least two faculty members, who together cover both data science and subject matter expertise. At least one of the supervisors is a member of the MacDATA Institute.

Two of the projects will be completed in collaboration with the Michael G. DeGroote Initiative for Innovation in Healthcare’s (MGDII) Innovation, Commercialization and Entrepreneurship (ICE) program. Experts at the Institute will work with the fellows to identify commercialization opportunities and assist with the development a business plan. It’s part of the Institute’s mandate to increase health innovation within the School of Medicine and the McMaster community.

Learn more about entrepreneurship and commercialization in academia though MGDII workshops and its monthly “Innovators” speaker series. Contact Sarrah Lal for more information.

Michael is a second year Ph.D. student and Vanier Scholar in the Department of Mathematics and Statistics working under the supervision of Dr. Paul McNicholas. Recently, he has been looking at developing methodology for an important data science problem, i.e., the analysis of three way data. During of the course of this fellowship, which will be co-supervised by Dr. Kathy Georgiades, Michael plans to apply clustering and classification techniques to better understand social inequalities in child and youth mental health and associated academic outcomes, specifically in migrant groups.

Sophiya Garasia
Senior Immigrant Health in Ontario

Sophiya Garasia is a Ph.D. student in the Health Policy Ph.D. program at McMaster University in the Health Economics stream. Her research interests lie in areas of health equity, health economics and quantitative methodology. Sophiya’s MacDATA project, which will be supervised by Emmanuel Guindon, Arthur Sweetman and Kathy Georgiades, focuses on health care outcomes and health care utilization trends in immigrant seniors compared to Canadian-born seniors. Data will be obtained from multiple cycles of the Canadian Community Health Survey (from 2000 to 2015) and linked to a number of datasets. The results of this research could have implications for decision making in the areas of ethno-specific long-term care in Ontario and immigration and social policies targeted toward immigrant seniors.
