Olga Dyakova did her halftime PhD defence on December 17. Olga brilliantly answered some very difficult questions from the committee, calmly debated equations on the black board (while every other student in the audience almost fainted from fear), and convincingly showed the committee and the audience that she has a complete understanding of her work. She did so amazingly well, and I am so proud to be a part of the start of her scientific journey.
