How do I abbreviate the titles after my name? I just got my Ph.D and I'm trying to work out how to do the full series of abbreviations after my name.

My scholastic qualifications are:


Ph.D University of New South Wales, Philosophy
Masters of Science, Rochester Institute of Technology, Information Technology
Bachelors of Science, RIT, Information Technology

RIT Scholar (University Medal)
Highest Honors.



Given that I have both American and Australian degrees, what series of abbreviations is appropriate to put after my name?
This varies between countries.  My impression is that listing titles after the name is more common in the UK and Australia, and there may be fixed conventions as to the ordering, but I can't address that.  What I can deal with is the U.S., and my advice in that context is simple: don't do it.  In the U.S., if you list one title ("John Smith, Ph.D."), you'll look a little pompous and like you are overemphasizing your degree (leading to questions like "Gee, is that Ph.D. still his proudest achievement?" or "Does he worry people will think he didn't get a Ph.D.?"), and if you list more than one it will look ridiculous.  In particular, don't list titles after your name in academic job applications, CVs, signatures for letters of recommendation, etc. that are being sent to the U.S.  Of course, conventions in other countries may be different.
