APS units are your opportunity to network with colleagues of similar interests, find collaborators and mentors, and stay informed of new developments in your specialized fields and regions.

Connect on Engage

Engage is a platform exclusive to APS unit members, where you can connect with other unit members, network online, participate in community discussions relevant to your field, and more. Unit leaders can also find the APS Unit Handbook and more resources on Engage.

We invite you to learn more about APS units on their websites, and log in to your myAPS account to join the unit that best fits your interest.
