PhD, Ph.D., Dr.
In English, PhD can be written with or without periods; both are correct. The trend today is to drop periods with abbreviations of academic degrees. However, many sources, including the Canadian Oxford Dictionary, still recommend the use of periods: Ph.D.
When you are addressing a person with a doctoral degree, it is considered more polite to use the title Dr. or the academic abbreviation PhD with the person’s name, instead of the simple courtesy titles Mr. or Ms.
Note: Do not use both the title and the degree. If the degree is listed after the name, the title is not used before the name.
