OHDSI Community Calls can be a forum to share research findings, present and seek feedback for active works-in-progress, demonstrate open-source software tools under development, debate community best practices for data modeling and analytics, and brainstorm future collaborative opportunities for grants/publications/conference workshops. If you are a Collaborator with a topic for an upcoming OHDSI Collaborator meeting, you are invited to post your thoughts on the OHDSI Forums.

 ### OHDSI Workgroups
 OHDSI has a variety of ongoing projects lead by workgroup teams. Each workgroup has its own leadership team which determine 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. Workgroup meeting cadence is determined by the project leadership and will vary from group to group. A list of the active workgroups is maintained on the [OHDSI Wiki](https://www.ohdsi.org/web/wiki/doku.php?id=projects:overview). \index{workgroups}
