Discipline Categories

Can’t find a topical session that fits your abstract? No problem! In addition to topical sessions, we
offer the following discipline categories. Discipline sessions are equally vital to our technical program
and are an essential addition to the fulfillment of the overall meeting. Encourage your friends to submit a
