PhysPort is a professional development website for physics faculty to develop their teaching through research-based resources. As part of PhysPort's ongoing research efforts, we conducted interviews with 23 physics faculty from diverse instructional and institutional contexts in the US. From our interviews, we sought common experiences, motivations, and pain points to develop personas--person-like constructs--of physics faculty in the US. Our research focuses on the perspectives of the key users of our site, and thus we take a user-centered perspective rather than a researcher-centered perspective. We developed personas, which are person-like constructs that are developed based on salient characteristics of actual users, that enable designers to create resources to meet actual user needs without designing for the idiosyncrasies of specific users. We present our set of six personas of physics faculty members: a faculty member who is new to improving his teaching; one who takes up his department's practices; one who wants her teaching to feel good; one who is comfortable in her teaching; one who is continuously improving; and one who solves big problems in her department. These personas of physics faculty making changes to their teaching can be used more broadly to improve the design and development of professional development resources and activities for physics faculty.
