Ms Kazuyo Machiyama, MPH, PhD

Assistant Professor

United Kingdom

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.

Research

I have conducted research on fertility, family planning, maternal health, unintended pregnancies and demographic dividend in sub-Saharan Africa and Asia. My PhD was on the re-assessment of fertility trends in 17 sub-Saharan African countries. This research included the development of a new trend estimation method adjusting for common errors in Demographic and Health Surveys (DHS), and the assessment of changes in proximate determinants of fertility in the past two decades. Recently, I am extending my interest to infertility, childless/child-free and access and quality of fertilty treatments in UK and other regions.

I am a member of Editorial Committee of Studies in Family Planning.
