Be inclusive and respectful when you name someone.
Use the style of name that the person uses for themselves, where known. For example, use Tom Jones if that’s what they go by, not Thomas Jones.
Avoid titles and honorifics as part of a name. Not everyone uses a title, and it’s easy to misgender someone if you make assumptions.
If absolutely necessary (for example, to establish credentials) note that anyone who has been awarded a doctorate is entitled to use the prefix Dr. Be led by the style they use themselves.
