After 35 busy and fruitful years in the Department, Professor Michael Struwe will be giving his farewell lecture on 13 October. In the following interview, he speaks about his early years as a young professor, the four awards he has won for his teaching and his time as one of the founding fathers and, subsequently, as director of the Zurich Graduate School in Mathematics.
