Zining Wang, an international student from China, was granted his master’s degree at the completion ceremony in September this year. Immediately after entering the university, he had a hard time because he could not come to Japan due to the restrictions on international movement due to the new coronavirus pandemic. However, taking advantage of this situation, he changed his research theme and decided to work on mathematical simulations with the cooperation of Professor Mochizuki and Professor Inoue of Kyoto University. He plans to continue to deepen his research in the doctoral course. We are all looking forward to his future research.
