During the 2016-17 academic year, Caltech recognized 25 faculty members with the Institute's most distinguished award for individual faculty—a named professorship. This honor provides faculty with additional funds and resources to pursue their best ideas while continuing to mentor future generations of leaders.

Each named professorship brings with it its own distinct legacy. Many chairs, for instance, have longstanding histories, and pass through each appointment a tradition of exploration and discovery from one academic generation to the next, from one colleague to another. Chairs sometimes also provide faculty with an opportunity to forge meaningful relationships with the philanthropists who provided the donation that made the endowed chair possible.

Caltech is pleased to present the 2016-2017 cohort of named professors.
