Despite its nearly 5,000 attendees, the Meeting is noted for maintaining its “small meeting” feel beginning with the Saturday Subgroup symposia, which allow attendees to meet within their scientific communities. It is also known for its vitality, demonstrated by the over 600 highly interactive daily poster presentations, the more than 500 speakers selected from submitted abstracts, the many career development programs for those working in academia, industry, and agencies throughout the world, and its advocacy and education programs.
