Presidential Poster Competition

The Presidential Poster Competition is an event where high-scoring trainees who are presenting-authors of a poster presentation compete among their peers. This competition is designed to award trainees for excellence in the field of endocrinology. Expert faculty members serve as Poster Judges to evaluate presenters on their poster quality, presentation skills, scientific rigor, and impact. The winners listed below were awarded the highest marks in their respective area.
