About ASCI membership

Membership to the ASCI is by election only and is considered an extraordinary honor in academic medicine and industry. Each year, ASCI members nominate those they feel have had significant accomplishments at a relatively early age — 45 or younger in their careers. The age limit — indeed, the Society itself — was established to provide a forum for younger researchers at the time (the early 1900s) by which to present their work. Meetings of scientific societies in the early 1900s were one of the primary modes of communicating findings, and established societies limited their membership (and, hence, those who could present research results) to more senior researchers. The ASCI distinguished itself by limiting induction to the Society to younger researchers.
