Many of the graduates of the Department of Biological Sciences play active roles as key members in universities and other research institutions. The chart below shows the post-graduate career paths of 559 master's graduates and 185 doctoral graduates from the two former departments between 2013 and March 2020. It indicates that 45% of master’s degree holders went on to the doctoral program, and that more than 44% of PhD holders began careers in research and relevant positions.

As the need for experts with knowledge and research experience at the master’s level or higher is increasingly recognized in today's complicated society, the opportunities for graduates of Biological Sciences to show their skills are expected to increase further. The entrance examination for the master’s program (the top 84 are accepted) is held in late August annually; about half of the successful applicants are from different departments or other universities. The entrance examination for the doctoral program for those from other institutions (only a few are accepted) is held in early February annually.
