At Symposium this year, we have put together a large number of on-demand sessions for you to view at your convenience. To maximize your time during Symposium weekend, we have set up “lecture viewing” blocks (about 2 hours per day) to watch on demand sessions.  We have also scheduled time to explore the expo hall, see the research poster session, visit the career fair, and attend other live events. Please see our schedule of live events here:  We have several live Q&A sessions or workshops that are being held to answer any questions about material presented in an on-demand session. If you are interested in attending a live Q&A or workshop, we recommend watching the on demand session prior to attending the live Q&A.
