The main purpose of this post-graduate course is to cultivate doctors in various fields of clinical medicine who are not only highly qualified in a chosen subspecialty but also are well prepared to pursue academic carriers. To meet this purpose, students will be selected from doctors who have finished at least three years of residency training with good standing. In addition to the clinical training, they must have published at least one paper which is equivalent to a master's thesis in quality.

The courses consist of subspecialty training, research studies and understanding of basic sciences related to the subspecialty. The program requires three to seven years for graduation. Besides a doctoral dissertation, a total of at least 35 credits are required. After written examinations of necessary courses and the defense of a doctoral dissertation, a degree of Doctor of Philosophy is conferred.
