My main area of research interest is improvement of reproductive health and minimising adverse effects of population changes on health and welfare worldwide. In the past few years, I am extending my interest to infertility, childless/child-free and access and quality of fertility treatments in UK and other regions.

My first degree was in Political Science from Meiji University in Japan and then I obtained a Master of Public Health with concentration in International Health from Boston University in USA. I completed a PhD in Demography at LSHTM.

I worked with a wide range of organisation from NGO to government and international organisation. Prior to joining LSHTM, I worked at the Non-communicable Diseases (NCDs) Unit in the World Health Organization Regional Office for the Western Pacific. I also worked at the African NGO, African Development and Emergency Organisation (ADEO), and conducted a fertility and child survival study in a Sudanese refugee camp in Northern Uganda. Before my career in public health, I worked for the Embassy of Japan in Uganda, Japan International Cooperation Agency (JICA) Headquarters, and JICA Indonesia with focus on evaluation of development programmes in Indonesia.

I work at LSHTM part time on Thursdays as Programme Director for the Nagasaki University-LSHTM Joint PhD programme, and work as Senior Research Manager at the Human Fertilisation and Embryology Authority (HFEA), UK, for the rest of a week.
