T EACHING E XPERIENCE“Physics Laboratory” (Undergraduate, 1st and 3rd year, Waseda U.)

Oct.2023-Feb.2024

I lead the physics laboratories on Vacuum (construction of the B-A gauge and checking the vacuum
level) for 3rd year level, and light (Young’s double slit experiment, polarization, and diffraction) for the
1st year level.
“General Physics B” (Undergraduate, 1st year, Waseda U.)
Oct.2023-Feb.2024
This covers the properties on waves (wave function, wave equation, standing waves, and physics onMusic instruments) as well as the properties of light (refraction, interference, and diffraction).
“Intermediate E&M” (Undergraduate, 2nd year, Waseda U.)
Oct.2023-Feb.2024
This course focuses on multi-dimensional non-relativistic electricity and magnetism. At the end of thecourse, as an entry to electrodynamics, Maxwell’s equations in vacuum, and simple electromagnetic
waves are studied.
“Research Design and Analysis” (Undergraduate, 2nd year at Waseda University) Oct.2023-Feb.2024
The introductory subject of experiment planning/information gathering. Students learn to collect information on the topic, plan experiments, and execute analysis and discussion of results in various ﬁelds ofscience. I taught how to conduct research in astronomy through my research on observations of supermassive black holes.
“Astronomy Graduation Research” (Senior at Tohoku University)
Apr.2020-Mar.2021
Each student will give a summary 1 hr talk of one chapter of introductory astronomy textbook written in
English. Through this course, students will be expected to learn basic knowledge on galaxies and active
galactic nuclei. Students will also conduct a basic research project assigned by supervisor(s).
“Astronomy Seminar” (Junior at Tohoku University)
Oct.2019-Feb.2020
Each student gives a summary 1 hr talk of one chapter of introductory astronomy textbook written in
English. Through this course, students learned basic but essential knowledges on astronomy, such as
magnitude, redshift, and the idea of the order-of-magnitude.
“A half year to be Professional Astronomer” (1st yr at Tohoku University)
Apr.2019-Sep.2019,
Oct.2022-Mar.2023
Through the semester, students have experienced how the professional astronomers conduct research,such as reading papers, picking up the research ideas, analyzing the data or conducting simulations, andgiving a presentation of results. Until now, we did a research on “What is the future of our milky way
galaxy?” and tried the simulation of the future of the milky way and the Andromeda galaxy collision byusing the GADGET simulation code.
