We perform clinical epidemiology and pharmacoepidemiology studies in all clinical areas utilizing various large scale Japanese-based medical or health checkup databases. The purpose of research projects is to identify the outcomes and safety of drug, surgery, medical device, and therapeutic regimen.

Research and Education

Researchers and students in the department conduct various research projects based on their clinical questions, such as outcomes research in clinical epidemiology and pharmacoepidemiology, to evaluate safety and the effects of medicines and medical devices on development and post-market. Most of the students has experienced with physician, surgeon, pediatrician, anesthesiologist, or pharmacist. We fully support students who aim to be distinguished researcher or professional in the field.
