CollaborationFest 2026 will be a collaborative work event at which participants work together to contribute code, documentation, training materials, and challenging analysis problems and use cases. If you are interested in learning and contributing in an intensely collaborative environment, then CollaborationFest is for you. Bring your own project ideas or come ready to collaborate with others on their projects!
BOSC has organized CollaborationFests (aka CoFests) every year before or after ISMB since 2010. The 2026 CoFest will start the day after ISMB 2026, in a nearby location in Washington, DC.
Dates and Location
Friday July 17 to Saturday July 18 (right after ISMB 2026), 9:00am - 5:00pm both days.
The location is in central Washington DC. The address will be shared with those who register.
How to sign up
Due to space constraints, participation in CollaborationFest is limited. Participation is free, but registration is mandatory. A registration link will be available shortly.
We encourage you to register for ISMB, but the CoFest itself is free. Three easy steps to sign up:
- add yourself to this spreadsheet to help us gauge interest, coordinate topic groups and logistics
- add your project ideas to this document if you have something in mind
- join the #cofest2026 channel in the OBF Slack!

Cost
CoFest is free to attend, but no food or drinks will be provided.
