3. Doctoral and Master's Courses

1). 4-year Ph.D. Course in the Department of Medical Informatics and Economics at the Division of Social Medicine
  The Department of Medical Informatics and Economics at the Division of Social Medicine offers the Medical Sciences doctoral course (4-year program) and admission is open to those who graduate from a 6-year program at the Faculty of Medicine (the School of Medicine), and those who complete the master course either in the University of Tokyo or any other institutions (not necessary to be a doctor). Students will acquire Doctoral Degree (Ph.D.) of Medical Science with completion of required units and passing a doctoral thesis.


2). 3-year Ph.D. Course and 2-year M.H.S course in the Department of Health Informatics at the Division of Health Sciences and Nursing

  The Department of Medical Informatics and Economics is a collaborating department with the Division of Health Sciences and Nursing at the Graduate School of Medicine, and it is called the Department of Health Medical Informatics.  At the Department of Health Medical Informatics within the Division of Health Sciences and Nursing, the department offers the Master course in Health Science and Nursing (2-year program) and the Health Sciences and Nursing doctoral course (3-year program). In the master course, students will acquire Master of Health Sciences with completion of required units and passing a master’s thesis. In the doctoral course, students will acquire Doctor of Health Sciences(Ph.D.) with completion of required units and passing a doctoral thesis.


3). 2-year M.P.H and 1-year M.P.H in the Department of Health Informatics in the Shool of Public Health

We offer 2-year Master of Publics Health (M.P.H) course and the 1-year M.P.H program in the School of Publics Health. See the homepage of the Shool of Publics Health.

4). 2-year M.M.S in the Department of Health Medical Informatics in the Medical Science Graduate Program

 Graduate School of Medicine, the University of Tokyo, offers the master course in Medical Sciences. The course was established for students who graduate from faculties other than a 6-year program at Faculty of Medicine and eventually wish to advance to the Medical Sciences doctoral course of the University of Tokyo. It enables students to enroll in the department they plan to carry out their research for Doctor of Medical Science. (the entrance examination required for enrollment in Medical Sciences doctoral course) In this Master’s course, all students entering the course spend the first four months taking formal coursework for students of all divisions, and then will decide which department they wish to affiliate with. At the department students are expected to conduct their research for the Master and complete a master’s thesis in the last one and an half year. They will acquire the Master’s degree (in Medical Sciences) with completion of required units and passing a master’s thesis. Our department also accepts students in this course.

 

4. Research Activities
Our main research domains are
1) application studies on developments of clinical information systems, hospital information system and electronic health records system
2) studies on medical safety infromation systems
3) medical knowledge discovery and analysis of medical economics indicators by using databases of hospital information system and electronic health records system
4) structured representations and standardization of medical terms and concepts
5) privacy protection and security in healthcare information systems
6) information analysis on food safety
7) analysis of various issues on DPC.

In these domains, major research topics are as listed below.
1) A study on development methods for large scale medical ontology databases of medical terms and concepts :
This research develops the methods to build the large scale medical ontology, which is a database for hundreds of thousand of clinical terms and concepts and their relationships. It focuses on the development of basic methods for making and accessing databases and will be applied for the research.

2) A study on the development of a patient-oriented, event-driven, and intellectual clinical support subsystem (Industry-academia collaboration project with Fujitsu Limited, 2004-2009) This research develops autonomic, distributed, realtime clinical support system. This system will be tested by being incorporated in the information system of the university of Tokyo Hospital.

3) A study on Natural Language Processing of Clinical Document (Industry-academia collaboration project with Fuji Xerox Limited, 2007-2010). This research is on extracting medical knowledge such as time-oriented clinical events and adverse drug reaction of patients from electrinic medical records.
