Anis Sharafoddini

Director, Data Science and Innovation

Educational background

I have a background in both Biomedical and Electrical Engineering, holding bachelor’s degrees in each. My interest in health sciences led me to continue with a Master’s in Biomedical Engineering, and eventually a Ph.D. in Public Health and Health Science from the University of Waterloo. This path has helped me work across different areas where health, technology, and research come together.

My past accomplishments

I have experience in both the private and public sectors. I began my career at Deloitte, one of the Big Four management consulting firms, where I worked with clients across healthcare, including pharmaceuticals, government, and hospitals. I focused on a range of data-related initiatives, from cloud migration to data science and analytics. I then joined Sanofi, where I worked on several innovative data projects. My passion for building data platforms eventually led me to Supply Ontario, where I co-led the development of a cloud-based platform to collect and integrate data from various organizations. In addition to my professional roles, I also serve as an Adjunct Faculty member at Northeastern University.
