I joined the Prof. Ishikawa theory group because they have outstanding theoretical expertise in the field of light-matter interaction, whether it’s atoms, molecules, or solids.  Here researcher can enhance their theoretical understanding of laser-matter interaction through discussions with professors and fellow researchers in a very calm learning environment. The fellow researchers and the staff are very cooperative and they try their best to help you. I’m really enjoying working here. If you are interested in this exciting field, please don’t hesitate to get in touch with Professor Ishikawa.
