    Research achievement→TRIOS

    The scope of research has much diversified from infectious disease control to population, nutrition, environmental and health systems research. The most challenging initiatives I am involving are in the studies of emerging and re-emerging infections, developmental origins of health and disease and climate change impact on health. I continue to be interested in finding effective and appropriate options for health interventions to control ill and health for the most vulnerable population in the world. We conduct the Critical Path Research (CPR) in the Tsukuba Clinical Research & Development Organization: T-CReDO. We aimed at patient-oriented clinical researches and their application, and foster professionals in various related fields essential for performing CPR.

  • Mizuho Fukushige

    Mizuho FukushigeAssistant Professor

    Research achievement→TRIOS

    I am an epidemiologist with interests in Neglected Tropical Diseases (NTDs), in particular, parasitic diseases such as schistosomiasis and leishmaniasis. I am teaching epidemiology and global health. In 2016, I obtained a PhD from the University of Edinburgh for my thesis on vaccine development and drug treatment for schistosomiasis: a systematic review and meta-analysis. Although my PhD study was mainly computer based analysis, I also have experience of epidemiological fieldwork activities for data collection in rural villages in Bangladesh as well as in Zimbabwe.


  • Takahiro Nunokawa

    Takahiro NunokawaDoctoral Program in Clinical Sciences

    I am a third-year doctoral student. I have worked as a physician and my subspecialty is rheumatology. I have a great interest in vasculitis and Pneumocystis pneumonia in rheumatic diseases. There are a lot of unsolved clinical questions in rheumatology. I would like to learn how to solve them in my PhD course. I grew up in Tsukuba before entering university. I am very happy to live here again.

  • Carolyn Kemonto Nyamasege

    Carolyn Kemonto NyamasegeDoctoral Program in Clinical Sciences

    My research interest is nutrition epidemiology because my background is bachelors in food nutrition and dietetics, masters of science in Applied Human Nutrition from The University of Nairobi, Kenya and an MPH from this department. Previously I worked with research institutions as a research assistant and later joined academics as a graduate teaching assistant and lecturer for a short period before coming to Tsukuba, Japan. My PhD research is on intervention effects on maternal and child health related outcomes in urban informal settlements of Kenya. Currently I am following-up a randomized controlled cohort.

  • Crispin Manda

    Crispin MandaDoctoral Program in Clinical Sciences

    I graduated from College of Medicine a constituent college of the University of Malawi. I studied Bachelor of Science in Medical Laboratory Science (Biomedical Sciences) in my undergraduate. I then worked at Zomba Central Hospital in Malawi for more than 3 years. This is where I developed interest to contribute to the development of strong disease surveillance systems which would strengthen evidence informed public health policy development and improve public health interventions. To achieve my goal I had to be able to produce scientific and technical information through research. Studying public health and epidemiology will therefore equip me with the much needed skills.

  • Farzana Ferdous

    Farzana FerdousDoctoral Program in Clinical Sciences

    My interests in general are in maternal and child health, etiology and epidemiology of infectious diseases, and life style as well as food habits related to non-communicable diseases. For my PhD, I would like to study maternal and environmental influences on intrauterine and early childhood organ development. As a public health professional, I would like to serve poorer people of my country as well as throughout the world. By enlarge I would ultimately be able to contribute towards global health.

  • Yuko Nozawa

    Yuko NozawaDoctoral Program in Clinical Sciences

    I am a first year doctoral student. I worked for a pharmaceutical company for eight years, after getting the master’s degree in pharmaceutical science. Through the experiences of clinical studies for medicines under development, I have felt I need to learn the skills further to design studies and evaluate the results appropriately. Now I am engaged in the clinical studies of a unique population in a new field and I am also interested in the design for the small sample size studies.

  • Genn Takayanagi

    Genn TakayanagiPhD student

    I am a second year doctoral student who belongs to a pharmaceutical company as a biostatistician. My Ph.D. study is to assess reliability (reproducibility) of a screening test of a certain disease based on statistical and epidemiologic approaches.

  • Nguyen Thi Ngoc Mai

    Nguyen Thi Ngoc MaiMaster of Public Health

    I am Nguyen Thi Ngoc Mai, currently in the second year for the Master of Public Health program. My primary research interest is chronic diseases and their effects on acute conditions. As the proportion of “old age” population has increased dramatically, it is expected that the burden of chronic conditions will continue to rise in the future. At the moment, we are working on using the Charlson Comorbidity Index to measure the burden of chronic comorbidity on community-acquired pneumonia’s outcome. Through this study, we hope to get more understanding of Japanese inpatient comorbidity pattern, as well as provide a way to control for these in the clinical setting.

  • Kiyoto Naito

    Kiyoto NaitoMaster of Public Health

    My previous research interests were radioactive material in the natural environment (especially in the river environment). And, I am interested in relationship between natural environment and human health and I want to know the skills to assess the effect of radioactive material on the human health and the society. In Tsukuba University, I want to tackle with problems related to the radiation disasters again and I hope to contribute to the society through my research.

  • Mai OzakiMaster of Public Health

    My interests are STI and reproductive health. Thus, I’m studying about how to prevent STI and methods of intervention.

  • Nobuyuki SaitoVisiting Researcher

  • Taro Nishimura

    Taro NishimuraMaster of Public Health program

    My general area of interest is in the epidemiology of neglected tropical diseases, and its effect on human health condition and society. However, currently, I am especially interested in the health-related problems which seem to be coming from the “absence” of parasitic infection. During my master’s study, I am looking forward to acquiring the basic skills needed for conducting the epidemiological studies and would like to have a better understanding of the latest issues related to the host-parasite relationship in humans.
