Webinars | Biostatistics@UHN

Biostatistics@UHN is pleased to offer a series of introduction to biostatistics virtual rounds for the 2023-2024 academic year. Each round will be led by one of our biostatisticians and will feature a Q&A session at the end. Rounds will occur virtually over Microsoft Teams every 3-4 Fridays at 11am.

Recordings and resources related to the rounds can be found on the Biostatistics@UHN Sharepoint page.

Rounds are free to attend. Registration is required.
