Shigekazu Takizawa


Ph.D. student (D2)

Biography

I like physical chemistry such as quantum mechanics and solid state physics, and I chose the Chemistry Department to study them broadly. Through lectures I found the principle of FT-IR spectroscopy to be interesting and smart, and then came to be attracted to other various spectroscopic techniques such as Raman spectroscopy, NMR, and nonlinear optics.

I'd like to develop spectroscopic techniques and devices with high speed to follow up short-time dynamics, high spatial resolution to study detail structures, and high sensitivity to detect a tiny amount of chemicals. Don't you think it's wonderful to become able to see mysterious phenomena we can't see before??
