04 A Special Round-table Looking Anew at Scientific Pursuit and Education at Keio’s Faculty of Science and Technology

From this April, Assistant Professors Takasumi Tanabe and Yoichi Kamihara returned to Keio, their alma mater, as faculty members while Assistant Professor Yoko Saikawa came back after a one-year study overseas. The three fresh researchers suitable for the new school year have been invited to talk about Keio University as a venue of scientific studies and education.


Keio as a venue of scientific pursuit

MC : Mr. Tanabe and Mr. Kamihara, both of you have joined Keio’s teaching staff from outside research institutions from this new school year. Will you tell us about your impressions of Keio: as seen from outside and as upon arrival at your respective posts?
Kamihara : A research institute is where people around you are all research specialists. All people working in the same field of study and having the same terminology at their fingertips – this is a very comfortable environment from the study perspective.
MC : I see.
Kamihara : But it is a very limited field. Of course the field we engage in contributes to society in a broad sense, but it remains a very enthusiastic field as an academic category. As a researcher, scientific research was the only work assigned to me, which sometimes made me worry about its value or significance. “Is my work really contributing to society?” “If so, is it appealing to the world?” . . . Questions like these.
      At Keio’s Faculty of Science and Technology, we rarely have two or more specialists in one specific field of study. The number of research fields is almost the same as the number of instructors. Accordingly many people say that they don’t quite understand what I’m doing. In this sense, the world of Keio seems to be broader and multi-faceted. To put it another way, being with Keio puts me in a bit better position to become aware of my position in society.
Tanabe : I had exactly the same impression as his. According to circumstances, the realm of my study not overlapping with others’ can be a demerit. But I think it’s possible to turn it into an advantage if I expand collaboration with outside researchers and other fields of research.
      Speaking of my impression upon arrival at my post, I can say Keio is filled with a very unrestricted atmosphere.
      It seems that Keio has great diversity. There are so many different types of people. It may be partly because there are various routes of entry. Take leading national universities for example. Most students there are survivors of entrance exam wars. Look around and you only find winners. In the case of Keio, however, some have come all the way through Keio from the elementary school level. Also there are those who have been admitted by recommendation. And some have passed the entrance exam with a strong wish to join Keio while others may have joined Keio “regretfully” after failure with other universities.
MC : That’s true. (laughter)
Tanabe : There are those who have experienced frustrations due to failure. The so-called “winners” can broaden their perspectives by knowing there are those that have experienced failure. Conversely, those having regrets may be encouraged or expand their scope of view by seeing other students enjoying bright campus lives. In my opinion, all these people with different experiences and mindsets getting together underlie Keio’s diversity.
      Seeing various types of people, with experience at both failure and winning, during college days makes students understand or become sympathetic to the feelings of many people. I’m sure it will prove valuable when they become leaders of society.
MC : What do you think Keio’s good points are in developing research activities?
Kamihara : When it comes to scientific pursuit, we shouldn’t hesitate to collaborate with other research institutes. Keio encourages such collaboration, which is good.
MC : What do you mean by “shouldn’t hesitate”?
Kamihara : At universities, there is only one specialist for each specific field of study. This creates the possibility that I may be the only source of inputs for my students, which is pitiful. Of course other teachers with specialties close to mine are around and available for advice, which is important. At the same time it’s important to communicate with outside people. In university’s peculiar environment, scientific pursuit wouldn’t develop fully if you hesitated to collaborate with the outside. We have to be outgoing. I’m always telling my students, “Go out and associate with outside people.” And it’s good that I can say so without hesitation.
Saikawa : Conversely, our department seems to be rather self-sufficient. There are as many as 30 teachers at our Department of Applied Chemistry alone, and our research fields range widely from those concerning compound structures to those involving elements of biology though within the framework of chemistry. Whenever you initiate something new, you can easily find good teachers right around you, who are willing to offer advice from the forefront of their respective specialties. Originally a graduate of Keio, I always feel at home here and see little barriers whenever I take up a new challenge. In this sense, I rarely feel it necessary to go out and seek information and technologies from various other fields.
MC : It sounds like there are differences according to departments . . .
Tanabe : With my department, too, there seem to be few overlaps, and I want to take advantage of it. In other words, I’d like to make the most of Keio’s merits as a university. Another point is the effective use of the many Keio graduates who are active in the industrial world. We shouldn’t forget that either. The work I’m engaged in is fundamental research. It takes a long time to put a project like mine to practical use. This makes it quite difficult even for specialists to envisage a route it will follow and what fruit it will eventually bear as a useful technology.
      In spite of such difficulty, I feel somewhat compelled to appeal my work to society. So, by receiving advice from various people actively at work in the industrial world, I’d like to say, “I’m now doing this. Is there any good way you can use it?”
Saikawa : Indeed, Keio boasts strong human connections between alumni and current students, even among senior Keio alumni.”
Tanabe : Yes, they do. Incidentally, next week I’m going to attend a “Mita Society” Keio alumni gathering organized at the company to which I previously belonged.

Keio as seen from overseas universities
MC : Ms. Saikawa, you studied at Harvard Medical School. What idea or feelings did you have when attending Harvard? And how did Keio look like when seen from out there?
Saikawa : Ever since I first joined Keio as an undergraduate, I’d had no chance to study overseas – engaging for years in similar research themes at the same laboratory. Harvard Medical School is literally a “medical graduate school.” As a person with little experience in traveling abroad, studying abroad itself was a challenge. So were the medical and biomedical fields that would be involved. Getting out of my laboratory appeared like a rare experience. “I will see and experience as many new things as I can” . . . this was the feeling I had before flying to the United States.
      I got this opportunity thanks to our department’s system that allows one young researcher to study abroad every year. Because of this system, I came to feel like studying overseas. It proved to be a truly precious opportunity for me since it would have been difficult to do so on my own.
      Once settled there, I was greatly impressed with Harvard in some aspects. I generally found the students enjoying their own campus lives while studying hard at the same time – a major similarity with Keio. When people asked me where I was from, quite a few of them knew the name of Keio. I got the impression that Keio was well known globally.
      If asked about my specialty, I am a person of chemistry rather than medicine. Not all researchers in the medical field are knowledgeable about chemistry, and vice versa. On occasion I saw chemistry still being held in high esteem in the world of medicine. Chemistry is a very old field of science whereas biology is gaining in popularity as of late. But I got the impression that chemistry is still a worthwhile pursuit.
MC : Importance of chemistry has been recognized again because you went to Harvard Medical School, you mean?
Saikawa : Maybe so. Discussions often become hot and mutually aggressive when talking with persons from medicine. It seems we talk at cross-purposes as the other party never sees problems from the perspective of chemical structure. But if we communicated thoroughly, both parties would come to understand and say, “Oh, I didn’t know about such a perspective.” In this way I could learn many new perspectives and approaches, which was a valuable experience.
Kamihara : Did you join any laboratory?
Saikawa : Yes, I did.
Kamihara : Does the medical school conduct clinical studies? Are there patients?
Saikawa : Some engage in clinical studies. But there are some Harvard hospitals in the adjacent area, so most of the clinically oriented engage in laboratory work there. Neurological studies are also conducted there. Patients never walk around in the area.
MC : And you came across some who knew the name of Keio, didn’t you?
Saikawa : Keio’s name was relatively well known at the medical school, which surprised me. When I was an undergraduate at Keio, I belonged to the Kendo Japanese Fencing Club, and this club had an alliance with Harvard. Presumably Keio is trying to approach Harvard. I could see similarities in school cultures as private colleges – the unrestricted atmosphere and so on. So I could feel at home at Harvard.
Tanabe : Keio’s Kendo Club in alliance with Harvard? Really?
Saikawa : Harvard students practicing kendo join Keio’s training camp.
Tanabe : You mean the Kendo Club . . . one of Keio’s sports clubs?
Saikawa : Right.
Tanabe : Great!
