My main area of research interest is improvement of reproductive health and minimising adverse effects of population changes on health and welfare in developing countries, particularly in sub-Saharan Africa. I currently conduct research on fertility, family planning, maternal health, unintended pregnancies and demographic dividend in sub-Saharan Africa. 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. 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. 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.

My Primary research interest is in fertility and reproductive health and the effect of fertility and reproductive health on the health and welfare of individuals, families, and the broader society. My current and recent research project includes:

1. Strengthening Evidence for Programming Unintended Pregnancy (STEP UP) (co-PI: Veronique Filippi)

Under this project, I am currently leading a multi-site cohort study on reasons for unmet need for fammily planning in Kenya and Bangladesh in collaboration with Africa Population and Research Center, icddr, b and Population Council. 

2. Systematic reviews on how health conditions during pregnancy, childbirth and the period following pregnancy affect health-related functioning  (PI: Veronique Filippi)

This WHO-funded project aimed to document the levels and patterns of health-related functioning deterioration as a consequence of health condition attributed to or complicating pregnancy, childbirth or the period following pregnancy. 

3. Unintended childbearing and family welfare in rural Malawi (PI: Angela Baschieri)

This research investigates the fertility intentions of both wives and husbands and the consequences of unintended childbearing on family welfare. The study is linked to the on-going Demographic Surveillance Site in Karonga district in Northern Malawi.

4. Population Analysis for Policies & Programmes

In addition, I contributed to development of a distance learning module on demographic methods

PAPP101 S05: Proximate determinants of fertility

PAPP104 S06: Measuring fertility preferences, unintended pregnancy and access to family planning

5. Sexual attitudes and lifestyles among university students in a low fertility society, Japan

In collaboration with Nagasaki University, this study aims to understand perceptions towards sex and romantic relationships, and explore determinants of and self-reported reasons for absence/existence of seeking a romantic behaviours and sexual contacts among male and female university students in Japan.
