I had my residency training in internal medicine in Tokyo, 1986-1988. From those days I was interested in working in Africa, which let me do DTMH in London, followed by a post-graduate clinical training in Harare Central Hospital, Zimbabwe, 1989 where I encountered my life work, AIDS. My master project on HIV viral load at LSHTM in 1990 was very successful that I was offered a job as a clinical research fellow at the Jefferiss Wing, St. Mary’s Hospital. My asset of multi-disciplinary human-network has been established when working in London, Oxford and West Africa for 8 years as well as in Tokyo at NIID for 3 years and in Thailand for JICA for 4 years.
I am the course director of Master of Tropical Medicine (MTM) where I teach clinical tropical medicine, malaria and non-malaria febrile illness, STD and HIV/AIDS. I also facilitate the tropical infectious disease case discussion.
As a chief of NEKKEN training/education center, I also organize the three-month diploma course of tropical medicine.
HIV research had been a core of my carrier before joining NEKKEN. It broadened my skills to understand a disease from multidisciplinary aspects such as behavioral, epidemiological, clinical science, molecular immunology and virology. Most of my work has derived from clinical-epidemiology settings such as cohort or case-control studies. I enjoy digging out clinical research questions by seeing patients and discussing with medical professionals. On joining to the current group of NEKKEN, my research topic has been broaden toward pneumonia in low, middle and high-income countries, non-malarial febrile illness such as typhus, leptospirosis. Now we have on-going studies in infectious disease wards in North Vietnam, the Philippines and Japan.

My asset is a human-network developed while working as a AIDS-researcher and a clinician in the UK MRC Laboratories, The Gambia, West Africa for 6 years. I then spent 4 years in Thailand for a JICA-project on HIV/AIDS; since became a professor of Nagasaki University, developed various clinical-epidemiology research projects in Vietnam, the Philippines and Japan; also have a role in the infectious disease ward at the University Hospital.
