This Week In OHDSI

The OHDSI community prides itself on global collaboration through open science. As a virtual community with collaborators on six different continents, we have weekly meetings to present research, share information, and keep each other updated on both current and upcoming projects. We hold these meetings on Tuesdays at 11 am ET in our Microsoft Teams environment. If you don’t have access to this, please fill out this form.

You can learn about our weekly calls, including the upcoming schedule of topics, and see materials (videos/slides/shoutouts) from previous calls by visiting our Community Calls page.

OHDSI has a variety of ongoing projects led by workgroups. Each workgroup has its own leadership team which determines the project’s objectives, goals and artifacts to be contributed to the community. Workgroup participation is open to all who have an interest in contributing to the project objectives and goals. Workgroups may be long-standing, strategic objectives or short-term projects to accomplish a specific need in the community. Each of the workgroups has its own home in the Teams environment, and you can get access to these groups by filling out this form (please note that you must have Teams access first, which is available through the first form linked above).

Please use our Upcoming Workgroup Calls page to see the upcoming schedule of calls (and appropriate links), as well as the standard schedule of calls for each group (weekly, bi-weekly, monthly, etc.).

We hope you will bring your talents, interests, curiosity and enthusiasm to OHDSI by joining both our weekly community calls and the workgroups that most interest you. That is how you #JoinTheJourney!
