Medical Doctorate
As the highest academic award in
medicine, the Medical Doctorate (MD) is designed to give formal public recognition to scholars who have made substantial, original and outstanding contributions to medical science as evidenced by their published work.
The MD is a higher doctorate gained by the compilation of published work on a coherent theme and is judged by national and international peers. It must demonstrate the candidate's authoritative standing in the field and achievements in the advancement of knowledge.
Entry Requirements
Students must hold one of the following degrees from this University:
* MBBS for not less than 7 years
* MMedSc or MPhil for not less than 3 years
* PhD in a branch of Medicine
Alternatively, a student may hold qualifications from another tertiary institution, for not less than 7 years, which is considered equivalent to the MBBS & has carried out a substantial part of the work associated with the proposed candidature at or in connection with this University.
-----------------------------
Obviously, this degree is for those physicians/surgeons who have produced a substantial amount of publications in international peer reviewed journals, have been practicing medicine for at least 7 years past obtaining their initial medical degree and are considered leaders in their field.
As far as the Master of Medical Science at Harvard, I am not sure it would be considered the equivalent of the research MD - Indeed, one of the entry points for eligibility to submit a research MD is completion of the MMedSc degree with at least 3 additional years of contribution past this. Like I indicated before, I do not believe that Americans award an equivalent degree. I still have yet to see an American degree that has the same requirements for admission and thesis submission as the research MD degree.
Finally, since the research MD is considered the highest degree in
medicine (per the above), and the MBBS the entry degree in medicine, when listing degrees it is customary to only list the highest degree if multiple degrees are obtained in the same field. I worked with many physicians who have the MBBS and MD (and one with both and a PhD, too) - all listed their qualifications as ---> My Name, MD, FRACP. (or --> My Name, MD, PhD, FRACP).
