Welcome to the Fons Research Group Homepage!
This is the home page of the Fons research group of Keio University Faculty of Science and Technology Yagami Campus. Welcome. On these pages, you will find an introduction ot the current and some past research. I am interested in a variety of different topics and always interesting in learning more about new things.
I would like to create an international environment for students working with me. Both English and Japanese languages are welcome. I will try my best to give students a different perspective filled with international collaborations. Please join me in learning more about the world.

Current Research Themes
There are several ongoing themes present in the Fons research group some of which are listed below. The basic theme is to understand atomic level structure and use the resulting understanding to optimize functionality. This includes the use of synchrotron radiation to investigate the physical and electronic structure of solids using tools such as x-ray absorption spectroscopy (XAFS) or high-energy photoemission spectroscopy. XAFS is a technique particular useful for understanding the structure of amorphous solids. Ultrafast dynamics has also been a topic of interest with collaborative efforts including using the free-electron laser SACLA at SPring-8, coherent phonon dynamics, or ab-initio molecular dynamics calculations. In addition to the use of ab-initio based computational techniques in recent years, the Fons group has used machine learning techniques both to predict good candidate materials for experiments such as selector materials as well as for the analysis of large datasets of molecular dynamic data. The use of machine learning techniques allows not only large improvements in the speed of analyzing large ab-initio computational datasets, but also large increases in the speed and size of molecular dynamics calculations by means of the use of machine-learned force fields based upon ab-initio calculations.
