Applying Evidence to Clinical Practice

After completing my master's program, I started working as a clinical psychologist in a psychiatric clinic. It was then that one of my senior colleagues, whom I admired, introduced me to the fascinating world of psychotherapy for sleep disorders.
The more I studied sleep disorders, the more I realized how important sleep medicine is in addressing the concerns of psychiatric patients. I was eager to apply this knowledge in clinical settings, so I started doing research.

【What are you most interested in lately】

Cultivating Epiphytic Ferns, Outdoor Activities, and Art

I have developed an interest in cultivating Platycerium, a type of fern, recently. I also enjoy Tenkara fishing and collecting affordable works of art from emerging artists. Supporting the art of younger generations is not only inspiring but also a way to express encouragement through my purchases. Or at least, that's my excuse for indulging in art acquisitions.

Making communication visible

Originally, I was interested in "reading emotions from facial expressions or vocal tone." However, during my studies in psychology at university, I began to consider that such ambiguous elements could become more tangible through numerical data or other visible forms. I started to think that this could potentially make life easier for some people or in certain situations. This led me to become interested in researching this area.

Movie watching/Photography

I enjoy watching movies, not only focusing on the characters but also savoring the landscapes and atmosphere. Lately, I've become obsessed with film cameras. It's enjoyable to experiment with different angles while taking pictures, especially within the constraints of limited exposures.

【Ongoing research】

Communication analysis in psychotherapy using multimodal data.


【Why did you become a scientist?】

Since my student days, I have had a strong interest in issues such as mental health and sleep problems faced by healthcare professionals. I am keenly aware of the importance of taking appropriate measures to address such issues and have a desire to conduct research in this field and contribute to society in any way I can in the future. In recent years, the remarkable development of applications and AI technologies has made it possible to take innovative approaches that make use of these technologies. I believe that by applying these cutting-edge technologies, I can find effective interventions that will contribute to improving the mental health and sleep quality of healthcare professionals.

【What are you most interested in lately】

I play guitar (both acoustic and electric).

Also, I have recently become addicted to whisky. I like to carefully make Whisky and Soda with a jigger and a muddler. Someday, I would like to visit the island of Islay in Scotland, the sacred land of whisky.

【Ongoing research】

  • ・Exploring Factors Related to Work Engagement of Nurses during the COVID-19 Epidemic.
  • ・The study of Generative AI-Based mental health care interventions for Nurses.

    Visualization of therapist-patient involvement

    I was thinking about how to interact with the patients I meet during clinical practice in my master's program. It was at this time that I learned about medical communication at a symposium at Nakajima PI.
    Currently, my aim is to communicate "what" and "how" to change behavior in the very complex situation of psychotherapy situations with evidences.

    Wearable Devices / Walking

    Recently I have been into using devices and apps to objectively verify my information. There are so many devices out there, and each one has its own unique and interesting features. On my days off, I walk around town or ride my bicycle.

    Acceptance of Researchers and Students


    Currently, the IIIS Nakajima Laboratory does not accept undergraduate students, but from April 2024, we will accept master's and doctoral students in the Psychology Degree Program (https://www.human.tsukuba.ac.jp/psychology/) of the Graduate School of Comprehensive Human Sciences of the University of Tsukuba. DC and PD students may also be accepted. IIIS also offers a five-year Ph.D. program "Graduate Program of Excellence"(https://www.jsps.go.jp/j-takuetsu-pro/), which brings together world-class teaching and research capabilities in systematic collaboration with domestic and international universities, research institutions, and private companies, for which Mr. Yanagisawa, IIIS Institutional Director, serves as program coordinator is also available. This program has a dual mentoring system, and if you are interested in interdisciplinary research, this is also recommended as a place to go to graduate school (Nakajima is not directly in charge of this program at this time, but please contact us). WPI-IIIS is a member of the World Premier International Research Center Program (WPI), which aims to become a globally visible research center, and has been adopted by the WPI Academy, an activity to position Japan as one of the poles of international brain circulation. Ph.D. students affiliated with WPI-IIIS are eligible for support from the WPI Academy (Research Assistant), and although not all students are, those who apply and are accepted can receive approximately 90,000 yen per month for master's students and 150,000 yen per month for Ph.D. students while working on research in the lab. (Recipients of public funds such as DC are not eligible.) In addition to WPI Academy Research Assistants, we also accept applications for Research Assistants and Research Assistants funded by ILCAA competitive funds, so please contact us if you are concerned about your financial situation.

    【Acceptance of Mentees and Research Assistants】

    We also accept mentees and research assistants who are interested in conducting research in their field. If you are interested in doing research but are not sure how to go about it, please contact us. We also offer assistance in obtaining competitive funding as a mentor, not limited to research areas. Both services are based on the premise of collaborative research. We can also accept unpaid research students to learn research while being involved in research.
