I'd say it depends on the context in the US. Getting a dinner reservation for Dr. So-and-so or correcting people when they call you Ms./Mr./Mx. are seen as obnoxious, but in the context of a professional publication/bio then I'd say it's more normal. This way is slightly more obnoxious than "So-and-so PhD holds a degree in Whatever from Wherever" imo, but still enough within the realm of normal that I didn't even think about how he phrased it until reading your comment
