If you are relatively new to the community or hope to have a bigger role, this is a great opportunity to introduce yourself. Please tell us who you are and where you work, what are your research interests, how you hope to help the community, and how OHDSI can help your own research journey. For scheduling purposes, please note your interest in taking part in this brief survey.

Tiffany Callahan (Senior Machine Learning Research Scientist at SandboxAQ) will provide a talk (July 31, 11 am ET) on ‘Agentic Mixture-of-Workflows for Multi-Modal Chemical Search’ during the next edition of The Center for Advanced Healthcare Research Informatics (CAHRI) at Tufts Medicine speaker series. This will be held on Zoom; please reach out to Marty Alvarez (malvarez2@tuftsmedicalcenter.org) if you are interested in joining the session.

• There is still time to let your voice be heard on the future of ATLAS. All surveys remain open and will help our ATLAS workgroup develop its future roadmap. You can find the surveys below, and they are also available on the ATLAS roadmap homepage, along with the demo videos.
