Taking on the challenge of various roles, as a team leader, an academic conference committee member, and a doctoral student

Terumi Umematsu
Principal Researcher
Biometrics Research Laboratories
Terumi Umematsu obtained her master’s degree in physics (specializing in measurement and control engineering) at university, where she conducted research on robot audition. When she joined NEC in April 2013, she became involved in research on speech recognition. Later, Umematsu shifted her research theme to affective computing, exploring technology to understand the health and internal state of people based on their voice. She currently leads a team as a principal researcher. Umematsu is actively involved in academic conferences and has earned recognition such as the Best Paper Award at the 2019 IEEE-EMBS International Conference on Biomedical and Health Informatics (BHI).

Estimating health conditions from facial videos
My current research is focused on the field of affective computing. Affective computing, which is a relatively new field of study, aims to improve people's lives and health while analyzing and respecting their internal state. To study mental and health conditions, it is not enough to simply handle data from an engineering and statistical perspective. Knowledge of medicine and psychology is also important, and social sciences that deepen our understanding of cultural backgrounds and social environments are indispensable. As such, affective computing is based on cross-disciplinary knowledge.
In the past, wearable sensors and microphones were used for sensing. Our team is developing technologies to estimate stress and arousal levels by sensing vital signs such as heart rate and oxygen saturation from facial videos captured by smartphone cameras and indoor cameras. As a leader, I find it very rewarding to promote research that has the potential to protect the physical and mental health of people around the world and contribute to their well-being.
That being said, NEC lacks knowledge and experience in areas such as medicine, psychology, and the social sciences. Therefore, our research team is actively conducting collaborative research with university hospitals and specialists in all over the country. In our research, it is important to collaborate with external experts in diverse communities in addition to relying on our internal team members.

Building a team that leverages strengths of individuals
In managing our team, I always try to bring out the best in each person and let the team members act on their own initiative. When our team deals with a new problem, I always try to leave it to my team member first. Our team is made of members from diverse backgrounds, and when each member brings their own ideas together, they often come up with innovative and outstanding approaches that I could never have imagined by myself. However, if we simply assemble a collection of individuals, we only get "one plus one equals two." I believe that we can maximize the synergy of the team by allowing the members to work together while appreciating individual initiative. My feeling is that everyone at NEC is really talented, so the best thing to do is to leave them to pursue their own initiative.
I actually learned this approach when I was stationed at the Massachusetts Institute of Technology (MIT) for a year and a half. I worked at MIT as a visiting researcher to prepare to start my research on affective computing through learning from the world's leading authorities. I was assigned there to conduct work for NEC.
In that laboratory, the style was to encourage each of the unique members to constantly express their opinions. The discussion driven by their energy was extremely stimulating. In a laboratory setting, professors tend to guide the research themes. Corporate research is similarly guided, and the discussions often do not venture far beyond meeting the needs of the customers or the wishes of the business divisions. I believe that new things capable of changing the world are born when talented team members can exchange opinions freely, rather than when discussions are restricted to some predetermined path.

Taking on the challenge of a doctorate program in addition to the role of academic conference committee member
I believe imagination is an important factor to develop cutting edge technology. As we increasingly become aware of diversity in our society, I always try to tell myself that my perspective is always limited. I am less likely to get stuck in my research as long as I am aware of the limitation. This is one of the reasons motivating me to actively participate in external activities, including academic conferences. In doing so, I can better understand what other organizations beyond the company are thinking and how NEC is viewed from the outside.
Last year, I served as a committee member for IEEE Women in Engineering in the Asia-Pacific region, and it was very exciting to learn how women think about and approach engineering overseas. I still serve on the Women in Engineering committee in Tokyo, and I carry out all of the activities on behalf of NEC as part of my professional duties.

In addition, I am also taking advantage of the discretionary work system to pursue a doctorate program for working professionals, which I attend on weekdays after leaving work, as well as on weekends. Although NEC has a domestic graduate school study system that offers tuition support for doctoral students, I chose to pursue my doctorate on a personal basis. All I wanted at the beginning was an environment where I could study something new while maintaining my effort and focus on my main job. I also thought that I might quit the graduate school without completing the program if this becomes too much of burden. This is why I joined the graduate school at my own expense.
When I started the program, I immediately forgot what I was thinking before (laughs). Although I came under a lot of pressure in the laboratory, my passion for the doctoral research and my desire for the doctoral degree become stronger than ever. I am now in my fifth year and will finally complete my degree examination this fall. I came to realize the importance of a doctorate through my experience overseas, so I want to keep going until I finish.

A day at work


Private column
My hobby is traveling. NEC allows us to take long vacations during Golden Week, summer, and the New Year's holidays, so I take advantage of these periods to go somewhere. I also spend many of my days off working on my university research. The opportunity to pursue research themes freely, which is different from how research is conducted at the company, is such a fun and rewarding experience. Someday, I hope to have the opportunity to study topics such as management and economics as well.
