David S. Bruce, Barbara A. Horwitz, & John M. Horowitz

In 2004, the American Physiological Society initiated two awards for excellence in undergraduate research: the David S. Bruce Outstanding Undergraduate Abstract Award and David S. Bruce Excellence in Undergraduate Research Award. These competitive awards are presented to undergraduate students who demonstrate excellence in communicating their research at the American Physiology Summit.

The Bruce Awards were initially established in memory of David S. Bruce, PhD, from Wheaton College to honor his commitment in promoting undergraduate involvement in research, the American Physiological Society annual meeting and research-related careers.

In 2017, American Physiological Society renamed the awards as the “Barbara A. Horwitz and John M. Horowitz Outstanding Undergraduate Abstract Awards” and “Barbara A. Horwitz and John M. Horwitz Excellence in Undergraduate Research Awards” in recognition of a generous gift from American Physiological Society members Barbara A. Horwitz and John M. Horowitz, who are strong supporters and mentors of undergraduate researchers.

Below is the Undergraduate Presenters at the 2026 David Bruce Undergraduate Poster Session and Horwitz/Horowitz Awards Ceremony recognizing the undergraduate researcher.
