To accommodate those who now have data ready to share and/or are able to attend, we are announcing a limited Abstract Submission for 15 days, starting Monday, January 3 at 12pm (noon) EST until Monday, January 17 12pm (noon) EST for the SMM2021 conference in Palm Beach, Florida on August 1-5, 2022. These new abstracts will undergo the same review process as all previously submitted abstracts. We anticipate all new abstracts submitted by in-person attendees will be presented in the poster format, as the oral presentation program is relatively locked in. However, some abstracts may be chosen as or changed to oral presentations subject to slot availability and quality of abstracts. For those unlikely to attend in-person, we encourage using this abstract submission period to submit for virtual presentation. This format allows for great flexibility and creativity of presentation for long and short formats. We look forward to seeing YOU in person or virtually. Regards, Amy C. Hirons and Jeremy Kiska, SMM2021 Co-Conference Chairs Stephen Trumble and Sascha Usenko, SMM2021 Co-Scientific Program Chairs
