In this laboratory, we study the structure of materials and their micro and macroscopic properties from electronic, atomic and molecular aspects, and aim to connect this expertise to development of various innovative materials, and become pioneers in the area of materials physics.


Research
Day by day our lives, societies, and the world around us are becoming increasingly more rich, comfortable and convenient. Still, the earth faces many challenging environmental problems and complex issues such as aging societies and we have to tackle these head on to solve them.
In the laboratory, we study the structure of materials and their micro and macroscopic properties from electronic, atomic and molecular aspects, and aim to connect this expertise to development of various innovative materials, and become pioneers in the area of materials science.
