The Scientific Program is now full. Please register with the understanding that new speaking opportunities are highly unlikely.
For the next Conference, we are enabling more participants to speak by having a mix of longer-format sessions with four speakers maximum in one hour (10 minute talks), shorter-format sessions on specific themes with 6-8 speakers in an hour (5 minute talks), and individual data blitz talks (5 minute talks) within variable-length Data Blitz sessions.
Please keep in mind the following organizational details when inviting colleagues:
- For the longer theme-based sessions, four speakers have 10 minutes for each speaker plus 5 minutes for questions. Session duration: one hour.
- For shorter theme-based sessions, speakers have 5 minutes plus 2 minutes for discussion. Session duration: 30 minutes or one hour.
- For the individual Data Blitz presentations: 5 minutes for each speaker plus 2 minutes for questions. Data Blitz session durations: variable.
- Please consider including both male and female participants as well as junior and more senior investigators in your session. We want to be an inclusive, democratic, non-hierarchical, and diverse meeting.
