Paris Grandes Écoles Team

ENS and UTokyo held a joint workshop on physics in Paris. From UTokyo, 8 faculty members and 1 professor emeritus participated and discussed about research and exchange possibilities. This year, 9 UTokyo graduate students and 1 research associate also participated in the workshop, and gave flash talks and poster presentations on their research.
