What is it like to be a Ph.D student at Kavli IPMU, in particle theory, with TW as an adviser?

Kavli IPMU

        Kavli IPMU (Kavli Institute for the Physics and Mathematics of the Universe) is a research institute that belongs to the University of Tokyo. Its research spectrum ranges from astronomy to arithmetic geometry. For more about the science we do, see the page of Research Programs. Kavli IPMU participates in the Ph.D program of the University of Tokyo, by having some of its faculty members appointed at the Physics Major Course of the Graduate School of Science, at the Graduate School of Mathematical Science, and at the Astronomy Major Course of the Graduate School of Science.

The admission channels I am committed to

        The Graduate School of Science at the University of Tokyo adopts a two-stage system in all of the addmission options for international students. Before the official selection by the Graduate School of Science, the applicants need to clear the pre-selection process run by individual faculty members appointed at the Graduate School of Science. In 20xx autumn, for students enrolling in September 20xx+1, I myself(Watari) and some other faculty members of the Physics Major Course run this pre-selection process jointly. If you are interested in choosing me as a prospective adviser, then you are invited to proceed to the page of the joint pre-selection process and follow the instruction there.

        As a policy of my own, I am open to the admission options for international students starting their Ph.D course in September (not for students starting in April). There are still a few admission options that the University of Tokyo offers. Among them, I open my window only through the GSGC course and the regular course (but not through the Government scholarships). I must ask for your understanding.

        Also as a policy of my own, I welcome international students to the Ph.D program only from the Master course, not directly into the Doctor course; this policy is also applied to domestic students. I know that some of the applicants have been finishing a Master course elsewhere at the time applying for the graduate study at U. Tokyo, but still I maintain this policy; see additional remark in the "Master Thesis and..." section below.

For Students Applying for the Enrollment in September, 2021

I have a couple of Ph.D. students to serve as a thesis advisor, and am fully occupied at this moment. So I will not be able to welcome one more student enrolling in September 2021 and serve as a thesis advisor every day.

At Kavli IPMU, there are two young faculty members---Prof. Tom Melia and Prof. Satoshi Shirai---in the field of particle theory. Both do not have a graduate school appointment at this moment, which means that they cannot be a supervisor officially, but conduct research independently from other faculty members, and are committed to our Ph.D. program. So, I am happy to host some students as the official supervisor, and make it possible for those students to be supervised by Tom or Satoshi in practice. If a student wishes to seek for such an arrangement, then he/she might think of including me (**) in the list of preferred advisor when applying to the preselection, and referring to such an arrangment (with the name of Tom and/or Satoshi) in the Statement of Purpose for the preselection.
(**) Some other particle theory faculty members at Kavli IPMU are also happy to provide such an arrangement with Tom and Satoshi.


Master Thesis and Qualification for the Doctor Course

There are a lot of things to learn in theoretical particle physics. So, in theoretical particle physics at the Physics Major Course, we do not necessarily require a graduate student to have produced an original scientific result for a master thesis. It suffices to write up a review article on a topic in this field to prepare himself/herself ready to be engaged in reserach projects soon after the master thesis defense.

We require (at least I definitely do), though, that a student has acquired basic ethics and skills of scientists, including honesty about what she/he is not sure about---(*), skills of critical thinking, logical thinking, and of exchanging ideas clearly (not just absorbing knowledge), by the end of the Master Course. If we are not sure whether a graduate student has been achieving that, we might recommend the student to leave academia without proceeding to the Doctor course.

(*) has been the first principle of academia, in Western as well as Asian World, not just in humanity but also in natural science.
      (Confucius) To take the things you know as what you know, and things you are not sure about as what you do not know yet, --- this is to know things. mVגmV, smוsm. m.
      (R. Feynman, a commencement address) The first principle is that you must not fool yourself, --- and you are the easiest person to fool.

As I wrote earlier (above), I ask all the students to go through this master thesis defense, even when one has finished a master course elsewhere before coming to the University of Tokyo graduate school. If such a student shows good enough performance, then we have an option to shorten the whole Ph.D. program (master course + doctor course) by 1 year.

We will authorize shortning the master course when the criterion above is met. It is not always the best option to do so for graduate students, though, because most of scholarship options in Japan for the doctor course (the latter half of the Ph.D program) do not cover extension beyond three years in the doctor course; graduate students need to be "ready" when entering the doctor course. An option of shortning the doctor course is approved by the Physics Major Course for truly outstanding students (on average, one student in five years or so?).
