Associate Professor Mikael Vejdemo-Johansson

It is with shock and sadness I heard the news today. Sayan was one of the pillars supporting my entire research field, and a great contributor both in research and in shaping one of the friendliest research areas I have met. He shone brightly, as a mentor, as a leader, as a teacher, and as a collaborator: one of the recent contributions I am most proud to have produced was in collaboration with Sayan, and the collaboration was fruitful and enriching in many ways. I will miss him.
