Hiroto Kitaguchi is a research fellow within the School of Metallurgy and Materials. His research focuses on quantitative and in-depth investigations of micro-/nano-microstructures by the applications of conventionally available analytical instruments, e.g. TEM, as the complementary investigation with atomistic-scale techniques, such as APT, to elucidate and rationalise physical phenomena in metallic materials.
